PROBLEM TO BE SOLVED: To provide an elastic spacer for force transmission arranged between a key top and an omnidirectional pressure sensor capable of correctly controlling a gap between the key top and a sensor. SOLUTION: The elastic spacer for force transmission, arranged between the omnidirectional pressure sensor and the key top, includes: a ring-shaped thick supporting part supported in relation to the omnidirectional pressure sensor; a circular thick central part contacting a lower surface of the key top; a ring-shaped thin middle part arranged to keep the gap between the sensor and the key top by elastically supporting the middle part from the supporting part so that the middle part faces upward; and a protruded part arranged on the lower surface of the middle part to face a pressure-sensing part of the sensor.
