After this bonding step, the base material 20 to which the phosphor bronze foil 11 has been bonded is subjected to electroless copper plating to establish continuity on the entire surface of the base material 20, and thereafter, as shown in FIG. Copper plating of appropriate thickness on the entire upper surface of material 20 2
Give 1. Since the copper plating 21 is applied to the entire upper surface of the base material 20 in this manner, it means that the phosphor bronze foil 11 and the copper plating 21 are electrically connected at this point. That is, the portion that will be the terminal 13 in the future and the portion that will be the print pattern portion 22 in the future will be connected.

After this copper laminating step, as shown in FIG. 6, the base material 20 is print-etched to obtain the print pattern portion 2
Along with 2, the terminal portion 13 and the contact 14 are made up by a known etching technique. Then, the etching resist 12 is removed.

After this etching process, a contactor processing step of separating the contactor 14 from the substrate 20 through the hole 20a and processing it into a predetermined shape is performed. If the contactor is processed into a socket type, The printed wiring board integrated connector 1 shown in FIG. 1 is obtained, and the printed wiring board integrated connector 1 shown in FIG. 3 is obtained by processing the contacts into pins.

In this embodiment, the phosphor bronze foil 11 is adhered to a part of the base material 20, but an elastic metal foil may be adhered to the entire surface of the base material. Further, the copper laminated on the base material may be overlapped at least at the portion of the metal foil bonded to the base material which will be the terminal. Further, in this embodiment, the hole 2
Although the base material 20 on which 0a is formed is used, a base material without holes may be used. In this case, in the bonding process,
The metal foil is adhered to the substrate, except for the portion of the elastic metal foil which will be a contact portion in the future.
