Provided is a low-cost optical module with highly consistent properties in an optical module that optically couples an optical waveguide array and an optical functional element array with lens optics. The optical module is characterized by being provided with, in a housing, an optical waveguide array having a plurality of first optical incidence ports and one or a plurality of first optical emission ports, an optical functional element array having one or a plurality of second optical incidence ports, lens optics using one or a plurality of lenses for condensing optical beams propagated between the optical waveguide array and the optical functional element array, and optically coupling the optical waveguide array and the optical functional element array, and a mirror disposed so as to convert the propagation direction of optical beams transmitted by the lens optics such that the optical beams are incident on the optical incidence ports of the optical functional element array. The optical functional element array is affixed to the housing directly or via a sub-mount or the like, and the angle of the mirror is fixed in place after the angle of the mirror is adjusted such that the optical waveguide array and the optical functional element array are optically coupled. |
