description PROBLEM TO BE SOLVED: To provide a method for manufacturing a miniaturized optical coupling element having a small mounting area and formed into J lead type, and a optical coupling element manufactured by the method. SOLUTION: The method for manufacturing a optical coupling element comprises a step for mounting a light emitting chip on a lead frame, a step for mounting a light receiving chip on the lead frame, a step for combining the mounted light emitting chip and light receiving chip to constitute an optical coupling element, a step for resin molding the optical coupling element to obtain an exterior molding 10a, a step for forming the lead terminal of the optical coupling element into J-lead type utilizing thick burr 17 between the exterior moldings 10a. The optical coupling element is manufactured by this method. The thick burr 17 is arranged substantially perpendicularly to the lead terminal 13 for light emitting element or the lead terminal 14 for light receiving element.
