Abstract

The invention relates to a touch sensor. A press sensor (11P) has a piezoelectric detection electrode (11P0), insulating substrate (11P1), base film (11P2), piezoelectric detection electrode (11P3), and insulating substrate (11P4). The insulating substrate (11P1) has an upper surface having the piezoelectric detection electrode (11P0) formed thereon, and a lower surface. The insulating substrate (11P4) has an upper surface having the piezoelectric detection electrode (11P3) formed thereon, and a lower surface. The insulating substrate (11P1) and the base film (11P2) constitute a piezoelectric film. The press sensor (11P) has a piezoelectric film that is provided with the piezoelectric detection electrode (11P0) and the piezoelectric detection electrode (11P3) on both the main surfaces. When viewed from the direction orthogonal to both the main surfaces, an opening (70) is provided in a center region of the piezoelectric detection electrode (11P3) that is provided at least on one of the main surfaces.

Description

technical field [0001] The present invention relates to a touch sensor for detecting pressing into an operation surface. Background technique [0002] Conventionally, various touch input devices have been proposed that detect an operation input when a user touches an operation surface. As a touch-type input device, there is a device that detects a touch position on an operation surface, and a pressure and amount of pressure on the operation surface. [0003] For example, the touch input device described in Patent Document 1 has a touch sensor in which a flat-shaped pressure-sensitive sensor (press sensor) and a flat-shaped electrostatic sensor are superimposed. The pressure sensor deforms in the thickness direction when the user presses the operation surface, and detects the pressure and the amount of pressure. The electrostatic sensor detects a touch position on the operation surface. [0004] Patent Document 1: Japanese Patent Application Laid-Open No. 5-61592 [0005]...
