Abstract:
An optical module comprising an optical device for converting one of an optical signal having a predetermined wavelength and an electric signal corresponding thereto into the other signal, an electronic circuit for processing said electric signal, and a lead frame having a lead pin connected to said electronic circuit;wherein a wiring substrate formed with at least a part of said electronic circuit is secured to one surface of said lead frame;wherein an electrode provided in said wiring substrate and a connecting portion provided in said lead frame are directly connected to each other, so that said electronic circuit on said wiring substrate and said lead frame are electrically connected to each other, said wiring substrate and said connecting portion of said lead frame being encapsulated with a resin so as to form an electronic circuit encapsulating portion; andwherein, in said electronic circuit encapsulating portion, a difference between a thickness of the encapsulating resin on said one surface of said lead frame from a surface of said wiring substrate opposite from said lead frame and a thickness of the encapsulating resin on the other surface of said lead frame is smaller than a thickness of said wiring substrate.
