PROBLEM TO BE SOLVED: To provide a heat conductive, pressure sensitive foam sheet not only excellent in balance between hardness and pressure sensitive adhesiveness but excellent in initial adhesiveness to exothermic bodies and having no time-dependent reduction of adhesiveness to the exothermic bodies and a method for producing the same. SOLUTION: The heat conductive, pressure sensitive foam sheet has dome-like protrusions on the surface. The method for producing the heat conductive, pressure sensitive foam sheet is to hold a foaming composition comprising a (meth)acrylic acid ester polymer copolymer, a (meth)acrylic acid ester monomer mixture, a heat polymerization initiator, a heat polymerization initiator, a heat conductive compound and a heat degrading foaming agent in a sheet-like state with a polyester film, and in the state, heat the composition in a temperature ranging from 10°C lower than the heat decomposition temperature of the heat degrading foaming agent to 10°C higher than the heat decomposition temperature of the heat degrading foaming agent.
