Abstract
A method for manufacturing a photocoupler includes: mounting light emitting devices and light receiving devices on a lead frame sheet; positioning the lead frame sheet with respect to a die by cutting off the one set of column portions from a linking portion and inserting a first pilot pin formed on the die into a second pilot hole; opposing the light emitting devices and the light receiving devices to each other; connecting the light emitting side coupling bars and the light receiving side coupling bars to each other on the die; forming a resin body so as to cover a pair of the light emitting device and the light receiving device; and cutting off the light emitting side lead frame portion from the light emitting column portion and cutting off the light receiving side lead frame portion from the light receiving column portion.
