This connector comprises: a connector main body mounted on a substrate; a latching piece that is attached to the connector main body and which temporarily joins the connector main body to the substrate by temporarily latching to an edge portion of an attachment hole formed in the substrate; and a rib having a width wider than the latching piece and which is attached to the connector main body. The rib is inserted into the attachment hole, and when external force in a direction of moving away from the substrate acts on one end side of the connector main body, whose end portions in the width direction interfere with the interior peripheral portion of the attachment hole, so as to generate resistance force that resists the external force.
