An optical communication module (A) of the present invention includes a substrate ( 1 ) having an elongated rectangular shape, a light emitting element ( 2 ) and a light receiving element ( 3 ) mounted on the substrate ( 1 ) to be arranged side by side in the longitudinal direction of the substrate, a resin package ( 5 ) which includes two lens portions ( 51, 52 ) respectively projecting in front of the light emitting element ( 2 ) and the light receiving element ( 3 ) and covers the light emitting element ( 2 ) and the light receiving element ( 3 ), and a shield case ( 6 ) for shielding the light emitting element ( 2 ) and the light receiving element ( 3 ) from electromagnetic waves and light. The optical communication module includes a surface extending in the longitudinal direction and serving as a mount surface for mounting on a mounting board (B). Each of the lens portions ( 51, 52 ) is covered by the shield case ( 6 ) in three directions, two of which correspond to the longitudinal direction of the substrate ( 1 ) and one of which is opposite from the direction in which the mount surface is oriented. |
