An optoelectronic device comprising: a plurality of light emitting elements; light receiving elements, each light receiving element facing a light emitting element; a lead made of a thin metal plate and having the light receiving elements fixed thereon, the lead being connected by wires to ground electrodes provided on the light receiving elements; a plurality of ground terminals common to the light receiving elements and integrated with the lead; an inner package, made of translucid resin, for separately sealing each pair of the facing light emitting elements and light receiving elements; and a package, made of resin having light interrupting properties, for sealing the entire inner package. Also, a metal mold that can simultaneously mold a plurality of the inner packages; and a manufacturing method of the optoelectronic device using the metal mold, comprising the steps of: molding the inner package; and then molding the package. Accordingly, a miniature optoelectronic device which has a small number of terminals and in which no crosstalk occurs can be achieved and efficiently manufactured.
