An optical pickup in which an actuator base is fixed to an actuator base fixing section of a housing is arranged so that a rigid body ball is provided in a gap between a side face of the actuator base fixing section and the actuator base, the rigid body ball pressing both the side face of the actuator base fixing section and the actuator base. With this, it is possible to prevent the relative positions of the actuator base and the actuator base fixing section from being misaligned.
