A battery sampling assembly, a cell fixing rack, a battery module, and an electric apparatus are provided. The battery sampling assembly includes a first sampling plate and a second sampling plate. A surface of the first sampling plate is provided with at least one first conductive sheet at one end and a second conductive sheet at another end, and a surface of the second sampling plate is provided with at least one third conductive sheet. In this application, the two sampling plates are separately provided with the conductive sheets, and the conductive sheets are directly welded to the surfaces of the sampling plates. Such design reduces space occupancy and allows for replacement for both wiring harness isolation and sampling wiring harnesses, so that relatively less components are used, and thus the volume of the entire module is reduced, and volumetric energy density of the battery module is increased.
