This light reception module is provided with: a semiconductor light reception element; a substrate which has the semiconductor light reception element mounted thereto, and which has, provided on a main surface, terminal parts which are electrically connected to the semiconductor light reception element; and a resin part which is optically transparent with respect to light of a prescribed wavelength, and which seals the semiconductor light reception element and the main surface of the substrate. The resin part is provided with: a first end surface which extends in a direction intersecting the main surface; a second end surface which faces the first end surface, and extends in a direction intersecting the main surface; and a third end surface which connects the first end surface and the second end surface, and which is parallel to the main surface of the substrate. The first end surface is a rough surface, and is exposed. The second end surface is inclined with respect to the main surface. The second end surfac
