Optical assembly

An optical assembly comprising:

• a circuit board including an electrically conductive path formed by printed wiring technology;
• a photoelectric conversion element connected to the circuit board via the electrically conductive path;
• a resin member made of light transmissive synthetic resin and attached to the circuit board, the resin member including a sleeve into which a ferrule attached to an end of an optical fiber is inserted and integrally including a lens through which an optical path passes, the optical path extending between the sleeve and the photoelectric conversion element;
• and
• a shielding member made of metal, the shielding member being connected to the circuit board and arranged to cover the photoelectric conversion element, the shielding member including a window through which the optical path extends to the photoelectric conversion element, wherein
• the shielding member includes a top plate, a side plate, and a board connection portion, the board connection portion extending from the side plate and elongated toward the circuit board, and
• the board connection portion is soldered to the electrically conductive path formed on the circuit board.
