Abstract
A laminated structure is formed by stacking a first block member, an intermediate member, and a second block member together in this order, and then mutually joining each of the members. Further, by setting the elastic constant of the intermediate member to be greater than the elastic constants of the first block member and the second block member, deformation of grooves, which are formed in the first block member, is minimized.
