Patent attributes
In a composite body, a frame body includes a frame member and a plurality of connection members formed by bending thin metal plates. The frame member includes a through-hole and extends along a peripheral portion of a substrate body. Each of the plurality of connection members has a first strip and a second strip continuously connected to opposed ends of a middle strip. The connection members are disposed in the frame member. Each of the first and second strips of the connection member is exposed on a major surface extending around the through-hole. The first strip and the second strip extend in a direction in which the connection members face each other, and opposed ends of the middle strip are continuously connected to the first strip and the second strip on the side adjacent to the through-hole. The middle strip extends through the inside of the frame member.
