Disclosed is an optical communication module including a module base in an approximately rectangular shape in which the light path member is introduce from one end surface in a longitudinal direction, a cover member provided at an upper portion of the module base and a plurality of pairs of conductive members in which each of the conductive members constituting a pair are respectively disposed at both outside surfaces of the module base and which are electrically connected to the light path member, and a concave portion is formed at an upper surface of the module base, the cover member is formed so as to cover an opening of the concave portion, and the conductive members are formed so as to extend for equal lengths toward an upper surface side and a lower surface side of the module base from a center line of a height direction of the outside surfaces.
