PROBLEM TO BE SOLVED: To provide a compact variable magnetic field magnetic therapy device that can be used by being directly stuck to a skin of a user, and can generate a variable magnetic field in a wide range even when the user does not move.SOLUTION: A variable magnetic field magnetic therapy device 1 that is used by being stuck to a skin H of a user includes: a container 2 having an internal space 21 and a bottom surface 24 that is brought into contact with the skin H when the variable magnetic field magnetic therapy device 1 is stuck to the skin H a magnet unit 3 rotatably stored in the inner space 21 and a rotation drive mechanism 4 for rotationally driving the magnet unit 3 in a plane roughly parallel to the bottom surface 24.SELECTED DRAWING: Figure 1
