An optical module including a plurality of laser diodes and outputting optical beams emitted from the laser diodes includes a radiator unit for radiating heat and a case enclosing the optical module. The case has a first attachment surface to which a red laser diode is attached, a second attachment surface to which a green laser diode is attached, and a corner part where the first and second attachment surfaces intersect with each other. The optical module has a first attachment part, for connecting the case to the radiator unit, in the vicinity of the corner part.

Optical module and scan-type image projection display device

A fixing structure of an optical component is composed of a device chassis; a holder holding an optical component; first and second plate parts for joint to the device chassis and a connecting part of both the plate parts are formed in the holder; a plurality of joint holes are formed in the second plate part; a U-groove into which the connecting part of the holder is fitted and a plurality of through-holes are formed in the device chassis; and an adhesive that is extended in a circular columnar shape and is made by inserting the holder into the U-groove of the device chassis, and applying a UV-curing adhesive in such a manner that the UV-curing adhesive is bonded to the first plate part of the holder and is continuous to the inside of the joint hole via the inside of the through-hole, and radiating UV light along the through-hole.
