Claims

[Scope of utility model registration request]

In an optically coupled semiconductor device that transmits a signal by directly irradiating light emitted from a light-emitting element facing a light-receiving element to the light-receiving element, the light-receiving element is connected to a first lead frame to which the light-emitting element is connected. The second lead frame has a frame portion having the same shape and dimensions except for the island portion and the terminal portion, and the first and second lead frames are superimposed and molded so that the frame portions are in close contact with each other. What is claimed is: 1. An optically coupled semiconductor device characterized in that it is packaged with
