PROBLEM TO BE SOLVED: To provide an electronic pen that allows for making an intended drawing by employing a switch configuration that can cope with intrusion of foreign materials and prevent quality degradation.SOLUTION: An electronic pen 1 includes; a switch unit 3 having a vibration sensor 32 that detects pressing force at a tip portion that is indirectly applied thereto; a light-emitting unit 2 that emits infrared light; and a circuitry unit 4 having a control unit that makes the light-emitting unit 2 emit light in response to the pressing force detected by the switch unit 3. The vibration sensor 32 is formed to be flexible and thus is deformed when tensile and/or compressive force, originating from the pressing force, is exerted thereon.SELECTED DRAWING: Figure 4 |
