The electrical connector includes a main body comprising an insertion opening into which a connection target is inserted and an accommodation space to accommodate the connection target inserted into the insertion opening, a conductive contact held in the main body so as to be connected to the connection target in the accommodation space, and a cover member rotatably mounted on the main body to be rotatable around a rotation axis passing through the main body. An insertion opening which extends along the rotation shaft and into which the connection target is inserted is provided in the housing. The cover member includes a release operation portion configured to receive an external force to rotate the cover member around the rotation axis, and a restricting member to switch, in response to the rotation of the cover member, between a first state in which removal of the connection target from the accommodation space is restricted and a second state in which the connection target is released. The insertion opening is spaced apart from, and opens away from, the rotation axis. A distance between the release operation portion and the insertion opening is less than a distance between the rotation axis and the insertion opening.
