Optical unit and image pickup apparatus having an optical device and a polymer actuator for moving the optical device

An image pickup apparatus, comprising an optical unit;

• the optical unit including:
• an optical system;
• an image pickup device having lead terminals;
• a polymer actuator which is provided in contact with the image pickup device so as to move the image pickup device;
• and
• electrical interconnection patterns which are provided on a surface of the polymer actuator wherein one of the lead terminals is connected directly to a first portion on one face of one of the electrical interconnection patterns, said first portion being located opposite to a second portion located on another face of the one of the electrical interconnection patterns that is held in contact with the surface of the polymer actuator;
• a focus detection section which detects a focus condition of a subject image provided by the optical system;
• and
• a drive section which moves the image pickup device in a direction of an optical axis of the optical system based on a detection result of the focus detection section by means of the polymer actuator,
• wherein the polymer actuator is disposed in contact with at least an opposite side of the image pickup device to an optical surface thereof, and the electrical interconnection patterns are provided on the surface of the polymer actuator which is in contact with the image pickup device.
