Abstract
A semiconductor optical device is provided with a photo-electric conversion unit having plural photo-electric conversion elements and is entirely sealed by a sealing member. The photo-electric conversion elements are connected to external leads with electrical connectors. The distance D between a planar outer surface and a photoelectric conversion area satisfies the equation, D.gtoreq./2.multidot.l/tan .theta., where .theta. is a critical angle of total reflection of the sealing member with respect to air and l is the maximum length of said photoelectric conversion area.
