Patent ID: 7674017

Claim:
An optical module comprising: an electric wiring substrate; a first optical element mounted on said electric wiring substrate so that a heat generation section of said first optical element is positioned relatively close to a substrate surface of said electric wiring substrate; and a heat sink mounted on the same plane as a mounting plane of the first optical element on said electric wiring substrate, said heat sink being mounted on said electric wiring substrate so that an area of electric wiring on said electric wiring substrate overlaps said heat sink, wherein said first optical element is made as a surface light-emitting type optical element while a light-emitting section of said surface light-emitting type optical element is mounted on said electric wiring substrate to be positioned relatively close as said heat generation section to the substrate surface side, a second optical element is mounted on a surface of said electric wiring substrate opposite to the first optical element mounting surface, and an optical propagation path is provided on said electric wiring substrate so that light emitted from said surface light-emitting type optical element propagates and arrives at said second optical element.
