  • the coil 24 and the pen pressure detecting unit 25 can be provided with a waterproof function by the inner body 1, the first sealing member 22, and the second sealing member 26. Further, the waterproof function can be realized by providing the protective layer 28B by UV bond on the circuit board 28 portion. These waterproof functions are not affected even if the main body holder 3 to which the electronic pen main body 2 is mounted slides and moves according to the writing pressure applied to the pen tip of the core 21, and is said to be the same. The waterproof function of the part will not be deteriorated or lost. Therefore, it is possible to add a waterproof function and realize a suitable electronic pen for use in a foldable terminal.
