The massage device contains several elongated massage elements with the working ends containing curvilinear contact surfaces. The opposite ends are joined as a support. The axes of the elements correspond to the sides of the imaginary truncated pyramid. The contact surfaces of at least part of the working ends contain the prominences in the area contacting the body surface to be massaged. These prominences locate in the apices of the imaginary polygon.
