Heat transfer suppression sheet, method for producing same, and battery pack

Abstract

A heat transfer suppression sheet contains a heat insulation material containing inorganic particles; an elastic sheet stacked on the heat insulation material; and a resin film covering the heat insulation material and the elastic sheet. The heat insulation material has a pair of heat insulation material main surfaces orthogonal to a thickness direction, the elastic sheet has a pair of elastic sheet main surfaces orthogonal to a thickness direction and elastic sheet end surfaces connecting the pair of elastic sheet main surfaces, the heat insulation material and the elastic sheet are stacked such that at least one of the heat insulation material main surfaces and the one elastic sheet main surface face each other, and at least one end surface of the elastic sheet end surfaces is pressed by the resin film to be inclined inward as being away from the heat insulation material.
