Abstract

See full text

An optical module according to the present invention comprises an optical element; and a multilayer insulating substrate which is a lamination of a plurality of single-layer insulating substrates and has a light transmission hole for passing light emitted from the optical element. The optical element is flip-chip mounted on the first outermost one of the single-layer insulating substrates. Each single-layer insulating substrate has a through-hole that constitutes a different part of the light transmission hole, the diameters of the through-holes of the single-layer insulating substrates increasing with drawing away the single-layer insulating substrates from the optical element.
