Claim Text:
1. An optical element module comprising: an optical element having a light receiving unit configured to input an optical signal or a light emitting unit configured to output an optical signal; a board on which the optical element is mounted; and a guide holding member that has a through hole into which an optical fiber including a core and a cladding is configured to be inserted for inputting and outputting the optical signal to or from the light receiving unit or the light emitting unit of the optical element, and is mounted and arranged to be aligned with the optical element in a thickness direction of the board; and an adhesive disposed between the board and the guide holding member, the guide holding member being mounted on the adhesive on the board, the adhesive being hardened to fix the guide holding member to the board; wherein the through hole has a cylindrical shape and has substantially the same diameter as an outer diameter of the optical fiber, a diameter of the light receiving unit or the light emitting unit is smaller than that of the core of the optical fiber; the optical element is flip-chip mounted on the board such that the light emitting unit or the light receiving unit is opposed to the board; the guide holding member is mounted on a surface of the board opposite to where the optical element is mounted; the board has a hole for transmitting and receiving the optical signal between the optical element and the optical fiber positioned on different surfaces; an inner diameter of the hole is equal to or larger than an inner diameter of the through hole; and the through hole includes an end portion facing the board and having a tapered shape.
