The invention discloses a massage belt, comprising a belt body formed by pressing a silica gel material with a hot-melt process, and a control module, wherein an inner ring of the belt body is press-fitted with a first conductive composite layer vertically symmetrically distributed about a central axis, the middle part of the inner ring of the belt body is press-fitted with six annular second conductive composite layers in annular distribution, a heating module and a low frequency pulse module which are connected by the control module simultaneously act, and the heating module can release infrared heat. The materials of the first conductive composite layer and the second conductive composite layers are used in combination with the low-frequency pulse massage module, and double effects of electric pulse stimulation and low-frequency pulse massage on a human skin joint can be achieved; the heating module and the low-frequency pulse module simultaneously act, and on the first conductive composite layer and the second conductive composite layers are used in combination with the low-frequency pulse massage module, a three-in-one effect is realized, and the physiotherapy effect is better.
