Input device

The present invention addresses the problem of providing an input device capable of easily distinguishing between two types of operations having different operation methods. The input device includes: a rigid board; a resin strain body fixed to the plate and having a long dimension direction; a key top placed on the strain body, and a strain sensor attached to the strain body. In the strain body, the thickness of the thin plate portion provided at both ends in the longitudinal direction is smaller than the thickness of the thick plate portion provided at the central portion in the longitudinal direction, the strain sensor is attached to the thin plate portion, and the strain body is fixed to the plate at the thick plate portion. 本发明的课题是提供能够容易地区别操作方法不同的两个种类的操作的输入设备。输入设备包括：刚体制的板；树脂制的应变发生体，固定于上述板并具有长尺寸方向；键顶，载置于上述应变发生体；以及应变传感器，装配于上述应变发生体，在上述应变发生体中，设于上述长尺寸方向的两端部的薄板部的厚度比设于上述长尺寸方向的中央部的厚板部的厚度薄，上述应变传感器装配于上述薄板部，上述应变发生体在上述厚板部处固定于上述板。
