Abstract: Provided is a connector capable of, when a closing operation of an actuator is mechanized, sufficiently applying rotational moment in a closing direction and preventing damage to the actuator. A connector (10) includes an insulator (30) into which a flat connection object is inserted, a contact group (40) that is supported by the insulator (30) and electrically connected to the connection object (20) inserted into the insulator (30), and an actuator (50) that is supported by the insulator (30) in an openable and closable manner, and also in a rotatable manner, and includes a connection object facing surface (52f) facing the flat connection object (20) in a closed state. The actuator (50) includes, on a surface opposite to the connection object facing surface (52f), a closing slope (52b) which reduces a distance to the connection object facing surface (52) as a distance from a rotation center of the actuator (50) increases.
