According to the fifth aspect, the second substrate (6) can be held on the main body (2) only by inserting the end portion of the second substrate (6) into the holding groove (210). However, this configuration is not necessary for the wiring device (10), and the holding groove (210) may be omitted.

The wiring device (10) of the sixth aspect is further provided with a supporting member (4) for supporting the first substrate (5) in the fourth or fifth aspect. The second storage portion (21) includes a support portion (a first support portion (211), a second support portion (212), a third support portion (213), and a fourth support portion (214)) that support the support member (4). ).

According to the sixth aspect, when the first outer terminal (18) and the first inner terminal (8) are connected, the support member (4) can bear the stress applied from the first outer terminal (18). However, this configuration is not necessary for the wiring device (10), and the supporting member (4) may be omitted.

In other words, the direction of the stress applied to the wiring device (10) can be limited to one direction (insertion direction). Therefore, the structure for receiving the stress applied from the first outer terminal (18) and the second outer terminal (19) can be provided only in one direction, compared with the direction of the stress applied from the first outer terminal (18) and When the direction of the stress applied from the second outer terminal (19) is different, the structure can be simplified.
