Abstract
An optoelectronic device containing a base plate, a first lead fixed to the base plate, a first bonding face for a light-emitting element fixed to the base plate and a second bonding face for a light-receiving element fixed to the base plate. The first and second bonding faces orient different directions. A top end part of the first lead protruding form the base plate has a third bonding face parallel to the first bonding face and a fourth bonding face parallel to the second bonding face. Each end of a first piece of bonding wire is bonded to the first bonding face and the third bonding face. Each end of a second piece of bonding wire is bonded to the second bonding face and the fourth bonding face. The wire bonding processes of the first and second pieces of bonding wire are performed between the parallel bonding faces, respectively, producing sufficient bonding reliability.
