Abstract: An object of the present disclosure is to provide an electronic pen that is excellent in portability by being reduced in size, that has a side switch functioning stably, and that is easy to maintain. A pusher part of an electronic pen body part is inserted into an insertion part of an operator, and the operator is thus attached to the pusher part of the electronic pen body part in a state of being fitted into an operator opening part of an outer casing. The operator opening part of the outer casing is formed in a side surface thereof at a position corresponding to a button switch of the electronic pen body part being loaded into the outer casing and placed at a fixed position. Therefore, the button switch can reliably be depressed through the operator, and the side switch of the electronic pen is realized.

Abstract: An electronic pen includes a circuit board disposed such that an axial direction of a casing is aligned with a longitudinal direction of the circuit board, an electronic circuit on the circuit board, and a battery having a columnar shape disposed on a side of the circuit board opposite to a pen tip side of the circuit board inside a hollow portion of the casing such that positive and negative electrode conductors protruding from an end surface of the battery extend toward the circuit board. The battery is disposed such that a separation space is formed between the end surface and an end portion of the circuit board and such that tip portions of the positive and negative electrode conductors are in contact with the circuit board. The circuit board and the tip portions of the positive and negative electrode conductors are electrically connected to each other by soldered portions.

Abstract: An electronic pen is provided that is enhanced in strength such as not to be bent or broken even when made to be thinner (smaller in diametric size). A connection section holds a core body at one end thereof and holds a circuit board at the other end thereof. The circuit board is accommodated in a board protecting pipe, which is fitted to the connection section. The board protecting pipe is provided with a side opening, and an operation on an electronic part on the circuit board accommodated therein and a work on an electronic circuit formed on the circuit board can be performed through the side opening. An electronic pen main body section wherein the core body and the circuit board and the board protecting pipe are united together through the connection section is accommodated in a casing, to constitute the electronic pen.
