Claim:
A composite substrate comprising: a substrate body having a terminal on at least a first major surface thereof; and a frame body connected to the first major surface of the substrate body, the frame body including a frame member made of an insulating material and a plurality of connection members defined by bent thin metal plates, the frame member having a through-hole at an approximate center thereof and extending along a peripheral portion of the first major surface of the substrate body so as to have a frame shape, each of the plurality of connection members having a first strip and a second strip continuously connected to opposed ends of a middle strip; wherein the plurality of connection members are disposed in the frame member so as to face each other with the through-hole of the frame member therebetween, the first strip is exposed on the frame member towards the substrate body and is connected to the terminal on the first major surface of the substrate body, the second strip is exposed on the frame member to a side remote from the substrate body, the first and second strips extend in a direction in which the connection members face each other with the through-hole of the frame member therebetween, the middle strip extends through an inside of the frame member, and the opposed end of the middle strip are continuously connected to an end of the first strip and an end of the second strip on the side adjacent to the through-hole of the frame member.
