Abstract
A shock absorbing laminate includes: a shock absorbing layer having an adhesive property and a stress relieving property; a heat diffusion layer having a thermal diffusive property, and a shield layer having electromagnetic interference shielding characteristics. The shock absorbing layer, the heat diffusion layer, and the shield layer are stacked on one another. The shock absorbing laminate which has heat dissipation characteristics and electromagnetic interference shielding characteristics and which can be affixed to another member without using the adhesive layer can be provided.
