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.
