OBJECTIVE LENS HOLDER, OBJECTIVE LENS DRIVING DEVICE USING THE SAME, OPTICAL PICKUP DEVICE, AND METHOD FOR MANUFACTURING OBJECTIVE LENS DRIVING DEVICE

摘要

Provided is an objective lens (OBL) holder and the like making it possible to easily supply an adhesive to a coil accommodated in an enclosure-shaped holder. An OBL holder of the present invention includes: a main surface portion provide with a fixing part on which an objective lens is fixed; and a first side-wall portion and a second side-wall portion provide with bobbins around each of which a tracking coil for driving the OBL holder itself by using a magnetic effect is wound. In the present invention, a communication hole provided in each of the bobbins penetrates the first side-wall portion and allows a region inside the OBL holder to communicate with the outside. A focusing coil is disposed in the region. This makes it possible to supply the adhesive to the focusing coil through the communication holes.
