Abstract: A pressing force sensor that includes a sensor element configured with a piezoelectric film, a lead terminal for connection to an external circuit, a wiring conductor which connects pressing force detection electrodes and the lead terminal, and a flexible printed circuit board which withstands solder reflow temperatures. The flexible printed circuit board has the pressing force detection electrodes formed on a first principal surface thereof, and is folded via a folding line while the first principal surface faces inward. The sensor element is deflected by a pressing force applied to a second principal surface which faces outward and is in a first area of the flexible printed circuit board which is on one side with respect to the folding line, and a signal corresponding to the pressing force is thus taken out from the pressing force detection electrodes.

Abstract: An electronic device with pressing input function includes a substantially rectangular parallelepiped-shaped housing. A pressure sensor, a display panel, a protective member, and an arithmetic circuit module are disposed in the housing. In the display panel, a front polarizing plate is disposed on a front face of a liquid crystal panel. The pressure sensor includes piezoelectric films having birefringence, and electrodes formed on opposed faces of one of the piezoelectric films . The pressure sensor is disposed between the liquid crystal panel and the front polarizing plate. The piezoelectric films are arranged such that their uniaxial drawing directions are orthogonal to each other.

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.
