Patent ID: 7419312

Claim:
An optical module comprising: an optical plug that supports one end of an optical fiber and has a first surface that is generally in parallel with an extension direction of the optical fiber at one end side thereof and two second surfaces traversing the first surface; an optical element container that has an optical element and a transparent surface traversing an optical axis of the optical element, and is disposed such that the optical axis of the optical element and an optical axis of the optical fiber cross one another; an optical block having an optical reflection surface disposed at an intersection of the optical axis of the optical element and the optical axis of the optical fiber; and a resin member that includes a first guide surface in contact with one of the two second surfaces of the optical plug and a second guide surface in contact with the transparent surface of the optical container on which the optical plug is mounted, wherein the resin member includes a thin portion having a first thickness relatively small in a first direction orthogonal to the optical axis of the optical fiber and a thick portion having a second thickness greater than the first thickness of the thin portion, wherein the second guide surface is formed as one surface of the thin portion.
