A composite material has plate (4) having holes (3) being bonded to a first member (1) to form an intermediate layer, and a second member (5) which is made of a material different from the first member (1) laminated onto the intermediate layer (2) while charging a portion of the second member (5) into the holes (3) of the intermediate layer (5) to form a composite material (6). The holes (3) of the plate (4) which forms the intermediate layer (2) have a shape such that the charged second member (5) exerts a resisting force against a tensile stress applied in a direction perpendicular to the surface of the first member (1), e. g. a shape having a first hole opened on the side of the second member (5) and a second hole communicated with the first hole having a space not overlapped with the first hole, or a shape that an opened area on the side of the second member (5) is smaller than that on the side of the first member (1). <IMAGE> |
