A composite member includes a metal sheet having a bent portion formed by bending, and a resin member joined to at least a part of the bent portion. The metal sheet includes an opening provided on an inner side of the bent portion, and a tapered recess that tapers off from an outer side of the bent portion toward the opening. The resin member includes an inner resin part filled in the recess, and an exposed resin part provided to be continuous with the inner resin part and to extend to an inner surface of the bent portion through an edge portion of the opening.

Composite member and composite-member manufacturing method

This invention relates to a light-receiving module in which transmission impedance of lead terminals are matched by simple method. The module has a semiconductor light-receiving device, such as a photo diode, a plurality of lead terminals for transmitting an electrical signal converted by the semiconductor device, and a metal base with a plurality of through holes, the lead terminals passes therethrough. The diameter of the lead terminal for signal transmission is smaller as compared with that of other lead terminal and the diameter of the through holes is adjusted and filled by a sealant glass with a dielectric constant so as to match the impedance thereof.
