An optical pickup device having an optical module provided with an optical
element and bonded and fixed to an optical pickup case, wherein the
optical module is fixed to the optical pickup case by a first ultraviolet
curing adhesive at at least two positions with an optical axis between
the positions, the optical axis extending from the optical element to the
optical pickup case, and at least a part of an exposed surface of the
first ultraviolet curing adhesive is covered with a second ultraviolet
curing adhesive higher in hardness or elastic modulus than the first
ultraviolet curing adhesive to diminish an optical axis offset of the
optical pickup device, further, a heat dissipating material higher in
thermal conductivity than the first and second ultraviolet curing
adhesives is brought into contact with both optical module and optical
pickup case to improve the heat dissipating performance of the optical
pickup device.
