    • An electric connector enabling multipolarization increasing the number of contact pieces by reducing a pressing force with which the contact pieces act on an actuator when the actuator is opened, including the actuator, the contact pieces, and a casing. The actuator includes an actuator body part and an actuator operation part. Each of the contact pieces comprises includes a top part beam, a contact beam, and a fixed base part beam. The contact beam and the top beam are formed in cantilever configurations. The contact beam opens the actuator so as to be pushed up when the actuator operation part touches near the free end of the contact beam to act a pressing force in one direction on the actuator operation part. The top part is pushed up when the actuator body part touches near the free end of the top beam to act a pressing force in the other direction facing the opposite direction of the pressing force to one direction of the contact beam on the actuator body part.
