The present invention provides a compact optic communications module. An optic communications module according to the invention can include a base including a portion defining a through-hole through a first plane to a second plane into which an optical fiber is inserted, a fiber optic piece located on the first plane side in the through-hole and whose axis length is shorter than the distance between the first plane and the second plane, a transparent resin film provided on the first plane of the base so as to cover the through-hole, a wiring film provided on at least one surface of the transparent resin film, and an optical element aligned on the optical axis of the fiber optic piece with the transparent resin film therebetween and coupled to the wiring film.
