Electromagnetic contactor

An electromagnetic contactor (1) is provided with an insertion port member (8) having an electric wire insertion port (8a) into which an electric wire (15) to which a connection terminal (14) is attached is inserted, and in which is formed a cylindrical section (8d) that constitutes an electric wire insertion path (P1) that is a path for the electric wire (15) inserted from the electric wire insertion port (8a). Furthermore, the electromagnetic contactor (1) has a second frame body (3) that has a partition plate (3a) that constitutes the wire insertion path (P1) by facing the end surface of the cylindrical section (8d) of the insertion port member (8) in the direction in which the wire is pulled out from the wire insertion path (P1), the second frame body (3) housing the conductive metal member (11) and a spring (12) that crimps the connection terminal (14) to the conductive metal member (11). A cylindrical section (8d) of the insertion port member (8) has a notch (8f) formed in the drawing direction in an en
