To provide an optical module that has no reflection problem even if an inexpensive optical fiber with a vertical end face is used and that facilitates alignment, and also to provide an aligning method of the same.
The optical module includes: one element of either an LD 3 for transmitting an optical signal or a PD 11 for receiving an optical signal; a stem 2 for mounting the element; an optical fiber 7 that is provided with a fiber end face 10 vertical to the longitudinal direction and that is optically coupled with the element; a ferrule collar 9 that holds the optical fiber 7, with the fiber end face 10 of the optical fiber 7 made parallel to a holding end face 9a; and a tubular housing 1 in which the stem 2 is attached to one end face 1a with the element inside and in which the holding end face 9a of the ferrule collar 9 is attached to the other end face 1b. In the formation of this optical module, the other end face 1b of the housing 1 is tilted at a prescribed angle to a face vertical to the optical axis 3a or the optical axis 11a of the element.
