Electronic pen

An electronic pen, comprising:

• a casing configured to be held by a user;
• and
• a side switch unit provided at a side surface of the casing, wherein the side switch unit includes an operating member configured to receive an operation input by the user,
• wherein the side switch unit includes a sensor unit in which two kinds of touch sensors of different detection systems are disposed such that respective sensor regions of the two kinds of the touch sensors are superimposed on each other,
• wherein the two kinds of touch sensors are a capacitive touch sensor and a pressure sensing touch sensor,
• wherein the capacitive touch sensor includes a plurality of capacitive touch sensors arranged in an axial direction of the casing,
• wherein the pressure sensing touch sensor consists of a single pressure sensing touch sensor configured to detect depression of the operating member by the user,
• wherein the plurality of capacitive touch sensors are interposed between the operating member of the side switch unit and the single pressure sensing touch sensor, and
• wherein the side switch unit includes:
• a holding member disposed within the casing and having an upper surface;
• and
• an elastic member disposed on the upper surface of the holding member and having an upper surface, wherein the operating member is disposed on the upper surface of the elastic member,
• wherein the sensor unit is disposed between the elastic member and the operating member.
