Thereby, it can suppress that the connector 10 attached to the fuel cell 20 moves to the left-right direction (stacking direction of a separator). Further, as shown in FIG. 14, the connector 10 is attached to the fuel cell 20 with the contact end side 21 c of the separator 21 in contact with the contact surface 200 t of the terminal 200. At this time, the contact surface 121 of the guide portion 120 sandwiches the separator 21 on the front side of the terminal 200. Therefore, when the connector 10 is attached to the fuel cell 20, the terminal 200 is separated at the center of the contact surface 200t. 21 can be in contact with the contact end side 21c.
- the connector 10 of this embodiment when the connector 10 is connected to the fuel cell 20, the terminal 200 comes into contact with the separator while being elastically deformed in the insertion direction of the connector 10, Occurrence of problems such as poor connection and damage when connecting the connector 10 to the fuel cell 20 can be suppressed.
