Abstract

Provided are a driver and a driver-integrated electric actuator that can suppress a temperature rise of the driver integrated with an electric actuator. A driver circuit of an electric actuator-integrated driver controls a current to be supplied to an electric actuator. A metal member (heat-conducting portion) conducts heat generated in the driver circuit. A driver sealing portion is fixed to the electric actuator and seals the driver circuit and the metal member. The metal member is extended to the electric actuator.
