Abstract

To provide a heat transfer suppression member capable of suppressing breakage of a battery case and a decrease in battery performance due to deformation of a battery cell while ensuring an interval between battery cells, and capable of suppressing propagation of heat between the battery cells at an abnormal state, and a battery pack capable of suppressing breakage of a battery case and a decrease in battery performance while suppressing propagation of heat between the battery cells. A heat transfer suppression member (50) includes a frame body (53) surrounding an outer periphery in a planar view, and a sheet-shaped heat insulation material (10) disposed in an inside of the frame body (53) and having a pair of main surfaces (10s). A thickness of the heat insulation material (10) is smaller than a thickness of the frame body (53) in a section view orthogonal to the planar view of the heat transfer suppression member (50).
