Abstract
An electronic device with pressing input function has a substantially rectangular parallelepiped housing. In the housing, a pressing sensor, a display panel, a protection member, and a computation circuit module are arranged. In the display panel, a polarization plate is arranged on a first side of a liquid crystal panel. In the pressing sensor, electrodes are formed on both planar faces of a piezoelectric film having double refractivity. The pressing sensor is arranged on the operation surface (the display face) side of the housing relative to the front polarization plate.
