Electronic pen

A method of manufacturing a circuit board for an electronic pen, the method comprising:

• forming, in a longitudinal direction of a flexible substrate, a circuit placement part at which a conductor pattern for a predetermined circuit is formed;
• forming a writing pressure detector placement part at which a conductor pattern for connection to the writing pressure detector is formed;
• forming a line part between the writing pressure detector placement part and the circuit placement part and at which a conductive line pattern electrically couples a component of the writing pressure detector and a circuit element of the predetermined circuit of the circuit placement part in such a manner that the circuit placement part, the writing pressure detector placement part, and the line part are arranged in the longitudinal direction and the writing pressure detector placement part is at an end part in the longitudinal direction;
• and
• placing an electronic component on the circuit placement part and placing at least part of components of the writing pressure detector on the writing pressure detector placement part, and soldering between the electronic component and the conductor pattern for the predetermined circuit and between the writing pressure detector and the conductor pattern for connection.

A method, comprising:

• placing and fixing at least a portion of a writing pressure detector on a writing pressure detector placement part, wherein a predetermined circuit is formed on a circuit placement part on a flexible substrate, and a line part is formed between the writing pressure detector placement part and the circuit placement part, wherein a conductive line pattern that electrically connects the writing pressure detector and a circuit element of the circuit are arranged linearly relative to each in a direction that extends along an axial direction of the circuit board, wherein the writing pressure detector placement part is located to be arranged on a side of a core body of an electronic pen;
• and
• coupling the circuit board to a holder, the holder including a housing part that houses the writing pressure detector such that the writing pressure detector is configured to receive a pressure in the axial direction applied to the core body,
• wherein the writing pressure detector placement part of the circuit board is inserted in the housing part from a direction orthogonal to the axial direction and the flexible substrate is bent at a portion of the line part.
