To provide an integrated circuit integral type actuator which can set the temperature of an integrated circuit to lower than an allowable temperature by suppressing the temperature rise of the integrated circuit.
The integrated circuit integral type actuator includes a connector (12) for inputting a power and a control signal, the integrated circuit (30) for energizing a coil with current larger than the control signal based on the control signal, the coil (10) for generating a magnetic field by energizing, a core (20) for constituting the route of the magnetic field, and a rotor (50) provided at the part of the core. In this integrated circuit integral type actuator, the coil is disposed at a predetermined side face part of the core. The integrated circuit is disposed at the side face part of the core at the opposite side to the coil. Or, the part of the core is brought into contact with other heat sink member. The integrated circuit is disposed on the core near the part (22) brought into contact with the heat sink member.
