The pen pressure detecting module includes a pressure sensing device, a first holder, and a second holder. The pressure sensing device senses the pressure based on a change in a capacitance formed between a first electrode and a second electrode disposed so as to be opposed to each other, which capacitance changes so as to correspond to the pressure that is transmitted to the first electrode. The second holder is housed in the first holder, and the pressure sensing device is disposed so as to sense the pressure applied to the second holder. An engaging portion engaged with a pressure transmitting member that transmits the pressure is formed in the second holder.Type: GrantFiled: April 22, 2014Date of Patent: December 6, 2016Assignee: Wacom Co., Ltd.Inventors: Masamitsu Ito, Ryoji Kamiyama, Shigeru Yamashita
