Abstract
An optical module has light source mounting parts that include a reinforcement plate for a circuit board on which a light source is mounted, and is attached to a lateral surface of a housing. The optical module includes a protrusion and a thermally conductive member. The protrusion is formed on the outer circumference of the lateral surface of the housing. The thermally conductive member includes a first surface and a second surface. The first surface is thermally conductively connected to a surface of the reinforcement plate. The second surface is thermally conductively connected to the protrusion. The thermally conductive member has an inclined surface on the back side of the first surface. The inclined surface is formed along the first surface in such a manner that the thickness between the first surface and the inclined surface increases with a decrease in the distance to the second surface.
