A work step of electrical connection between a writing pressure detecting unit and a circuit element of a circuit is reduced.;An electronic pen includes a writing pressure detecting unit that detects a pressure applied to a core body disposed on one end side of a tubular chassis in the axial center direction, a circuit board for which a flexible substrate formed into a shape allowed to extend in the axial center direction is used in the chassis, and a holder unit housed in the chassis in such a manner as to hold the writing pressure detecting unit and the circuit board and extend in the axial center direction. In the circuit board, a writing pressure detecting unit placement part, a circuit placement part at which a predetermined circuit is formed, and a line part at which a line pattern that electrically connects a component of the writing pressure detecting unit placed on the writing pressure detecting unit placement part and a circuit element of the circuit placement part is formed are formed to line up in the axial center direction. The writing pressure detecting unit placement part of the circuit board is held by the holder unit in the state of being along a direction perpendicular to the axial center direction in such a manner that the writing pressure detecting unit can receive a pressure in the axial center direction applied to the core body through bending of the flexible substrate at a part of the line part.
