1. An electronic pen comprising:
a circuit board;
an electronic part mounted on the circuit board;
a rigid tubular member that includes a side wall extending over an angular range of at least 180 degrees with an axis of the rigid tubular member as a center, wherein the side wall of the rigid tubular member forms an opening that extends over an angular range of less than 180 degrees with the axis of the rigid tubular member as the center, and wherein the circuit board is disposed within the rigid tubular member with the electronic part adjacent to the opening formed by the side wall of the rigid tubular member;
a pressure detector that is not surrounded by the rigid tubular member in a state in which the circuit board is surrounded by the rigid tubular member, the pressure detector being electrically connected to the circuit board surrounded by the rigid tubular member; and
a casing that is different from the rigid tubular member, wherein the rigid tubular member is disposed within the casing with the circuit board disposed within the rigid tubular member.
