1. An optical module comprising:
a first optical waveguide disposed parallel to a substrate;
a condensing mirror configured to reflect and condense light propagated in the first optical waveguide toward the substrate;
a second optical waveguide that guides the light reflected by the condensing mirror to a vicinity of a surface of the substrate, the second optical waveguide having a first end on the first optical waveguide side and a second end on the substrate side, the first end having a first diameter and the second end having a second diameter that is smaller than the first diameter, and the second optical waveguide formed in a tapered shape gradually narrowing from the first end to the second end; and
an optical function unit disposed on the substrate such that the light emitted from the second optical waveguide is incident on the optical function unit.
