Zusammenfassung:	Provided are a battery pack and a heat transfer suppression sheet for a battery pack that is used in a battery pack in which battery cells are connected in series or in parallel, and that can cool the individual battery cells during normal use while suppressing the propagation of heat between the battery cells when an abnormality occurs. The heat transfer suppression sheet (10) for a battery pack is used in a battery pack in which battery cells are connected in series or in parallel, and is interposed between the battery cells. The heat transfer suppression sheet (10) for a battery pack includes a heat-insulating material (11) containing at least one of inorganic particles or inorganic fibers, and a covering material (12) covering at least a part of the heat-insulating material (11). A sealed gap (14) is formed between the heat-insulating material (11) and the covering material (12), and the covering material (12) is configured such that a communication opening that allows the gap (14) to communicate with the outside of the covering material (12) is formed at a temperature of 60°C or more.
