A light emitting and receiving device structure capable of compactly accommodating a light emitting element and a light receiving element and having an optical axis of an emitted beam of light in close proximity to an optical axis of a return beam of light to produce the light emitting and receiving device in a miniature size and lightweight. A one-piece structure consists of a cylindrical package having a bottom with its one end open and the other end closed with a bottom plate and a protruding pedestal member which is installed on the bottom plate of the package with its centerline concentric with the centerline of the package. The light receiving element is secured to the front end surface of the pedestal member, while the light emitting element is secured to the side face of the pedestal member, thus accommodating both devices in one package.
