CONSTITUTION: An object lens drive unit comprises a moving structure (210), a yoke structure, a wire holder.(220), and a suspension wire (230). The moving structure comprises an object lens (11) and a driving coil (212). The yoke structure comprises a permanent magnet (224) which corresponds to the driving coil; yokes (225,226) which support the permanent magnet; and a fixing unit (223) which is extended from the yoke. The wire holder has a first surface to which the fixing unit of the yoke structure is integrally connected, and a second surface which is near the first surface and equipped with a terminal unit inside. The suspension wire connects multiple driving coils to the terminal unit of the wire holder. |
