  In the present embodiment, the circuit board 70 is disposed so as to constitute the bottom of the battery housing portion 92, and the mounting terminal 9 for mounting the test connector 820 is disposed on the portion constituting the bottom. Thus, it is possible to provide the mobile phone 1 as an electric device that can be used for an evaluation test and normal use without increasing the number of parts.

  Further, in the present embodiment, the bottom surface portion of the battery housing portion 92 is configured by the flat surface portion 73a that is a part of the circuit board 70, and the mounting terminal 9 to which the test connector 820 can be attached is arranged on the flat surface portion 73a. Therefore, at the time of the evaluation test, the test connector 820 can be attached to the mounting terminal 9 to perform the evaluation test, and the test connector 820 is detached from the mounting terminal 9 at normal times (other than the test). Thus, a normal battery 90 can be accommodated. Thereby, the evaluation test can be performed in a state approximate to the use state. Further, since the test connector 820 is not built in the operation unit side body 2, the mobile phone 1 can be miniaturized. Even after the mobile phone 1 is assembled, an evaluation test can be performed without disassembling. In addition, since the mounting terminal 9 is formed at a position covered with the battery 90 at normal times, the mounting terminal 9 does not interfere with other components. Further, the power from the test battery 91 can be used during debugging.

  Further, in the present embodiment, since the battery 90 is usually present and the mounting terminal 9 is formed in a portion where no component or the like is mounted, the mobile phone 1 can be downsized by an efficient mounting structure.

  In the present embodiment, an insertion portion is formed through which the flat cable 830 connected to the test connector 820 is inserted into the battery lid 25a that is mounted in a state where the test battery 91 is accommodated. Further, the mounting terminal 9 is formed on the side surface 93a side of the flat portion 73a, and the insertion portion is formed on the side surface 93a side of the battery lid 25a. Thereby, the flat cable 830 can be easily extended from the operation part side housing | casing 2, and an operation test etc. can be performed in the state approximated by the use condition.
