Abstract
To shorten the length of an electric wiring between a capacitor and a PD, and to improve high frequency characteristics. An optical module of the present invention includes a light receiving element disposed at such a position that light from an optical transmission path is received on a light receiving surface in a state that the light receiving surface faces the optical transmission path; a spacer jointed to the optical transmission path and to the light receiving element in such a manner that a gap between the optical transmission path and the light receiving element is kept at a predetermined distance that light from the optical transmission path is allowed to enter the light receiving surface; and a capacitor electrically connected to the light receiving element, and disposed along with the light receiving element on a surface of the spacer on the same side as that joined to the light receiving element.
