A package for an optical sensor device has a double-molded structure in which a first resin molded portion and a second resin molded portion are integrated. The first resin molded portion has a structure in which peripheries of a die pad portion on which an optical sensor element is mounted and a part of each of a plurality of leads are molded with a resin so as to be integrated, the part of each of the plurality of leads being embedded in and completely surrounded by the first resin molded portion. The second resin molded portion is molded over at least a portion of the first resin molded portion to form an outer shape of the package and has embedded therein and completely surrounds a part of each of the plurality of leads. A glass substrate having a filter function is bonded to an upper surface of the resin molded portions to form a cavity in which is mounted the optical sensor element.
