1. An electronic pen comprising:
a tubular casing;
a circuit board disposed in a hollow portion of the tubular casing such that an axial direction of the casing is aligned with a longitudinal direction of the circuit board;
an electronic circuit disposed on the circuit board; and
a battery that has a columnar shape and that is disposed on a side of the circuit board opposite to a pen tip side of the circuit board in the axial direction inside the hollow portion of the casing in a state in which positive and negative electrode conductors protruding from an end surface of the battery on one side in a centerline direction of the columnar shape extend toward the circuit board,
wherein the battery is disposed in a state in which a separation space is formed between the end surface of the battery from which the positive and negative electrode conductors protrude and an end portion of the circuit board on one side in the longitudinal direction and in which tip portions of the positive and negative electrode conductors are in contact with the circuit board,
wherein the positive and negative electrode conductors of the battery extend in a direction parallel to an upper surface of the circuit board and are disposed such that a distance between the positive and negative electrode conductors increases as the positive and negative electrode conductors are away from the end surface of the battery.
