The utility model discloses a battery module, a battery pack and a power utilization device, and relates to the technical field of power batteries. The battery module comprises a battery monomer, two opposite side plates and an adhesive tape. The plurality of single batteries are positioned between the two side plates, and each side plate extends along a first direction; the adhesive tape is arranged on the side face, facing the battery monomers, of the side plate in the first direction, and the side plate is connected with the battery monomers through the adhesive tape; the adhesive tape has a first thickness D1 in a natural state, and has a second thickness D2 after being compressed, and the first thickness D1 and the second thickness D2 meet the following conditions: 0.9 mm < = D1 < = 1.3 mm, 0.33 mm < = D2 < = 0.65 mm, and 9/25 < = D2/D1 < = 1/2. According to the battery module provided by the invention, the side plates and the battery monomers are fixed through the adhesive tapes, so that the control on
