Abstract

PURPOSE: To make the production method of a photo coupling device easyassembly and cheap.
CONSTITUTION: Light emission element 13 and light receiving element 14 are provided on same faces at the edges of lead frame terminals 12 and 12 which are extended in parallel in the same direction in one lead frame 11, and these terminals are connected electrically to other lead frame terminals 12 and 12 by wire 15. Next, edges of lead frame terminals 12 are dipped in the tank of transparent resin 16 such as epoxy resin, and an optical path between light emission element 13 and lighr receiving element 14 is formed. After that, they are further dipped in the tank of epoxy white resin 17, and the resin mold of both elements 13 and 14 is completed. Then, lead frame 11 is cut off from the part near the root of each lead frame terminal 12.
