| 1. An optical head device comprising:
a lens holder which holds an objective lens for converging an emitted light beam from a light source on an optical recording
disk;
a wire support body which supports the lens holder through a plurality of wires so as to be movable at least in a tracking
direction;
a drive magnet which makes the lens holder move at least in the tracking direction by a magnetic force generated between a
drive coil attached to the lens holder and the drive magnet; and
a plate-like member on which the wire support body is mounted, the plate-like member comprising:
a bottom plate part on which the wire support body is mounted; and
a rising part raised from the bottom plate part so as to face with a gap to a side face of the wire support body,
wherein the wire support body is subjected to surface bonding to the rising part with a first adhesive which is disposed within
the gap and mounted on the plate-like member; and
wherein the wire support body is adhered and fixed on the bottom plate part with a second adhesive at a lower end portion
of a side face which is opposite to a side face which is adhesively bonded to the rising part.
