  • Publication number: 20230205330
    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.
