PROBLEM TO BE SOLVED: To enable relatively easy manufacturing and smooth conduction of heat by a heating element to a heat sink without causing deformation of neighboring components. SOLUTION: A radiation sheet 11 is provided between a heating element 14 and a radiator 16. This radiation sheet 11 includes a plastic porous metal layer 12 having a number of pares, and a filler 13 filling a number of pores of the plastic porous metal layer 12 and having rubber elasticity and plasticity. It is preferred that the plastic porous metal layer 12 is a porous sintered body of Cu, Al or Ag having a porous ratio of 10-60%, and that the filler 13 is silicone rubber or polyolefin elastomer. |
