ELECTRONIC CIRCUIT MODULE AND PROJECTOR

摘要

PROBLEM TO BE SOLVED: To provide a technique for improving heat radiation efficiency in an electronic circuit module equipped with heat-generating components. SOLUTION: The electronic circuit module having heat-generating components and utilizing an air blow to radiate heat of the heat-generating components includes: a planar heat-radiating plate disposed so as to abut on the heat-generating components and radiate heat of the heat-radiating components; an opposite surface facing a heat-radiating plate opposite to an opposite surface of a surface abutting on the heat-generating components; and a protruding portion disposed between the heat-generating plate and the opposite surface to increase the flow rate of an air blow therebetween in the peripheral portion.
