Double faced adhesive tape structure, battery monomer, battery pack and electric device

The utility model relates to a double faced adhesive tape structure, a battery monomer, a battery pack and an electric device. The double-faced adhesive tape structure comprises a main body thickening layer and an edge folding layer, and one end, in the thickness direction of the double-faced adhesive tape structure, of the main body thickening layer is constructed as a first bonding end; the flanging layer is stacked at the other end of the main body thickening layer in the thickness direction; wherein the edge folding layer comprises an edge area, the edge area is located at at least one end, in the width direction of the double-sided adhesive tape structure, of the edge folding layer, and the edge area is arranged in a protruding mode relative to the main body thickening layer in the width direction; at least one end of the edge area in the thickness direction is configured as a second bonding end. The double-faced adhesive tape structure provided by the embodiment of the utility model not only can protect a component covered by the double-faced adhesive tape structure, but also can reduce the probability of edge warping in the use process of the double-faced adhesive tape structure, so that the bonding effect of the double-faced adhesive tape structure is improved.
