In a hand type electric massage machine, a vibration head is connected through a coupling spring to a top end portion of a hand case, and an unbalance weight is rotatably mounted to a top end portion of a rotary shaft so that the center of gravity of a weight element is positioned on a line extending radially from a bearing of the rotary shaft. The weight element is fixed to a part of the periphery of a lower end portion of a cylinder base having nearly covered cylindrical form including a disc portion and a skirt portion extending downward from the periphery of the disc portion. According to another feature of the present invention, the longitudinal ends of the vibration head are respectively provided with a curved surface extending in a vertical direction and with a curved profection surface having a smaller radius of curvature than that of the above-mentioned curved surface and lateral sides thereof include a spherical surface member having an elastic body and with a spherical surface member having a number of small projections, respectively.
