ABSTRACT:
A lead frame of an optical coupling device of the present invention is so arranged that (a) a light-emitting side section in which a plurality of header sections for mounting thereon the light-emitting elements are aligned and (b) a light-receiving side section in which a plurality of header sections for mounting thereon the light-receiving element are aligned, and (c) a connecting section for connecting the light-emitting side section and the light-receiving side section in parallel into one body. The light-emitting side section and the light-receiving side section are integrated via a connecting section at which a V groove is formed for facilitating the folding of the lead frame. As a result, it is possible to provide a low-cost lead frame of an optical coupling device with a small number of components can be realized, in a simplified manner, and a manufacturing method of the optical coupling device.
