Abstract
A large number of ventilating apertures that have a circular cross section are disposed through the heatsink so as to extend from an air intake apertured surface to an air discharge apertured surface so as to have aperture directions that are parallel to each other and parallel to an element mount surface, and the heatsink is disposed such that the air intake apertured surface faces an air intake aperture and the aperture directions of the ventilating apertures are aligned in a direction of flow of a cooling airflow.
