Optical module

摘要

An object is to suppress precipitation and adhesion of an organotin compound in an optical module which is incorporated into an optical pickup device and so on. The optical pickup 100 includes light sources 1, 10, optical components 2, 3 transmitting light emitted from the light sources, a driving circuit 28 for driving the light sources, that is electrically connected to at least one component other than the driving circuit using solder 27a, 27b containing a flux, and heat radiating members 22a, 22b for radiating heat generated in the light sources 1, 10, wherein the heat radiating members 22a, 22b can generate only ethanol, or ethanol and methanol so that a proportion of ethanol is more than that of methanol.
