<p>PURPOSE:To provide an optically coupled device having a high breakdown strength at a low cost in which the number of parts can be reduced and a manufacturing process can be simplified. CONSTITUTION:Both of a light emitting device 2 and a light receiving device 3 respectively mounted on a lead frame 1 are placed, and both of the devices 2 and 3 are respectively potted with a rubber transparent resin 10, and an optical coupling path is formed between both of potting parts by a gel transparent resin 11.</p> |
