The present application relates to the field of batteries, and provides a fixture, an isostatic pressing apparatus, and a battery production device. The fixture comprises at least two clamping plates and a pressure assembly. The clamping plates are stacked in a first direction, and a packaged electrode assembly is located between any two adjacent clamping plates. The pressure assembly is configured to apply pressure to the clamping plates in the first direction, so that any two adjacent clamping plates move close to each other. Each clamping plate comprises a support layer and a flexible layer stacked in the first direction, the flexible layer is located on at least one side of the support layer close to the packaged electrode assembly, and the hardness of the flexible layer is less than the hardness of the support layer. During isostatic pressing, a pressurizing medium pushes the clamping plates to apply pressure to the packaged electrode assembly to achieve densification processing. The support layer has relatively high hardness, enabling the clamping plate to possess certain hardness to apply pressure to the packaged electrode assembly; the packaged electrode assembly is in contact with the flexible layer, and the flexible layer has relatively low hardness, thereby reducing the possibility of damage to the packaged electrode assembly.
