This connector-mounting configuration comprises: a latching claw that is provided at a connector and latches to a substrate, whereby the substrate is equipped with the connector; a protruding portion that is provided so as to protrude from the latching claw and latches to the substrate, whereby the latching claw latches to the substrate; and a flexing portion that is formed from a first plate member that is a plate-like component and that is disposed at a position closer to the base end side of the latching claw than the protruding portion thereof. The flexing portion is disposed so that the plate thickness direction of the first plate member coincides with the protruding direction of the protruding portion.
