Optical connector having resin member including lens

An optical connector for use with an optical fiber, the optical connector comprising:

• a housing;
• a photoelectric conversion circuit board on which a photoelectric conversion element is mounted, the photoelectric conversion circuit board being housed in the housing;
• a resin member made of a light transmissive synthetic resin and arranged on a plate surface of the photoelectric conversion circuit board so as to cover the photoelectric conversion element, the resin member including a sleeve to which a ferrule attached to an end of the optical fiber is fitted;
• an inner board positioned in the housing at a side that is opposite to a side of the resin member with respect to the photoelectric conversion circuit board, the inner board being oriented substantially perpendicular to the plate surface of the photoelectric conversion circuit board;
• a flexible board electrically connecting the inner board and the photoelectric conversion circuit board;
• and
• a terminal connector connected to the inner board at one end portion thereof and connected to an outer board at another end portion thereof positioned outside the housing, the outer board being connected to the housing while being arranged along the axial direction of the sleeve, wherein:
• the flexible board is arranged to cover a surface of the photoelectric conversion circuit board opposite to a surface thereof on which the photoelectric conversion element is mounted,
• the flexible board includes a shielding layer over an entire surface of the flexible board,
• the sleeve of the resin member is arranged such that an axial direction thereof is substantially perpendicular to the plate surface of the photoelectric circuit board,
• the resin member integrally includes a lens on an axial line of the sleeve such that the lens faces the photoelectric conversion element, and
• the resin member further includes an inner shield, the inner shield being made of metal and being arranged to face the photoelectric conversion circuit board and cover the photoelectric conversion element, the inner shield including:
• a window at a position corresponding to an optical path extending between the lens and the photoelectric conversion element, and
• a board connection portion being connected electrically to a conductive path formed on the photoelectric conversion circuit board.
