PROBLEM TO BE SOLVED: To soften back pains or neuralgia, reduce stiffness, and make an unhealthy body due to an unfavorable blood circulation healthy. SOLUTION: Holes 2 are provided on a plate-form part 1 having a peculiar property of volume elasticity. Then, individual bodies having a different hardness from the plate-form part 1 are embedded in the plate-form part 1. Thus, by a difference in the repellent forces by an external pressure, the skin texture and the subcutaneous muscles are stimulated, and healthy effects are generated by this structure.
