With reference to FIGS. 1 to 4, an embodiment of an electric circuit having an electric component and an electric experiment set will be described.
As shown in FIG. 1, the electric circuit 10 includes a planar wiring 13 having conductivity, and a battery component 20 and a light emitting component 30 as electrical components that are electrically connected to each other via the planar wiring 13. The battery component 20 includes a battery 21 as an electric element that is a power source, and the light emitting component 30 includes a light emitting element 31 as an electric element that emits light when electricity flows. In the present embodiment, the electric circuit 10 has a circuit configuration in which two battery components 20 are connected in parallel to the light emitting component 30. That is, each positive electrode of the two battery components 20 is electrically connected to one (left side in FIG. 1) planar wiring 13 and each negative electrode is electrically connected to the other (right side in FIG. 1) planar wiring 13. Has been. Further, the positive electrode of the light emitting component 30 is electrically connected to one (left side in FIG. 1) planar wiring 13, and the negative electrode is electrically connected to the other (right side in FIG. 1) planar wiring 13. Therefore, in the light emitting component 30, the light emitting element 31 emits light by electricity supplied from the battery component 20.

  The planar wiring 13 is disposed on a non-conductive plane 12 provided on the surface of a plate-like support plate 11 made of a ferromagnetic material such as iron. That is, the flat surface 12 is a surface made of a nonconductive member on the surface of the support plate 11 that is a magnetic body. Although the flat surface 12 may be merely placed on the support plate 11, the flat surface 12 may be fixed to the support plate 11. If the plane 12 is fixed to the support plate 11, the support plate 11 is moved to an arbitrary angle including an angle other than horizontal, which is an angle other than 90 degrees with respect to the vertical direction, and is moved or transported. However, the flat surface 12 does not shift from the support plate 11.

A wiring with low resistance can be created simply by drawing a picture. This marker easily recognizes that the wiring is metal because the silver nanoparticles of the conductive material develop a metallic color. In addition, since this conductive ink dries quickly, is easy to apply, is not easily broken, and is resistant to bending and friction, it is suitable for forming the plane wiring 13 on the plane 12 having flexibility. Furthermore, since this conductive ink shrinks in the ink material when an overcurrent flows and is peeled off from the flat surface 12 to cut the circuit, it is difficult to generate heat and ignite, and the safety in the experiment of the electric circuit is high.
