HEAT TRANSFER SUPPRESSION SHEET, PRODUCTION METHOD THEREFOR, AND BATTERY PACK

To provide a heat transfer suppression sheet that can maintain a shape thereof, even when the heat transfer suppression sheet is pressed due to expansion of a battery cell, to thereby suppress a decrease in heat insulation performance, a production method therefor, and a battery pack including the heat transfer suppression sheet. A heat transfer suppression sheet contains: a first inorganic particle (1); a resin binder (6); and an organic fiber (3), in which the organic fiber (3) has a glass transition point higher than a glass transition point of the resin binder (6). In addition, at least a part of the organic fiber (3) is fused each other to form a three-dimensional framework (8), and a resin binder (9) is fused to a part of the framework (8) and at least a part of the first inorganic particle (1), and at least a part of the first inorganic particle (1) adhere to the framework (8).
