PURPOSE:To achieve a high-speed communication which has been only possible by a conventional chip carrier in a light-receiving single part for optical communication with a can type part which can cope with highly reliability. CONSTITUTION:The lead 3 of the cathode of the title element is provided at the center of a package. The stem has no mount base 2 which has been conventionally provided. The lead 4 of the anode is bent at right angles toward the light-reception element 1 side, thus enabling the light-receiving element 1 and the lead 4 to be bonded at an extremely short distance. Also, a portion which is constituted by a mold 66 at an outer periphery of a stem of the lead 3 and 4 and an insulation glass material is impedance-matched to the system.
