Abstract
[Object] To provide a pressure detection panel that allows suppressing the cost required for an FPC and obtaining in-plane uniformity of a detection signal of a pressing force even when a panel size is large. [Solution] A pressure detection panel 1 of the present invention includes a surface panel 2 and one strain sensor 3 arranged on a back surface of the surface panel 2 in a strip shape along one side of the surface panel 2. The strain sensor 3 includes sensitive units R1, R2, and R3 at an intermediate portion and both end portions in a longitudinal direction. The adjacent sensitive units, that is, the sensitive units R1 and R2 and the sensitive units R2 and R3, are mutually connected in series by a wiring line 31.

A pressure detection panel, comprising:
- a surface panel;
- and
- a strain sensor arranged on a back surface of the surface panel in a strip shape along one side of the surface panel, wherein
- the strain sensor includes sensitive units at an intermediate portion and both end portions in a longitudinal direction, and the adjacent sensitive units are mutually connected in series by a wiring line.
A strain sensor for use with a pressure detection panel, the strain sensor comprising:
- a first end sensitive unit;
- a second end sensitive unit positioned opposite the first end sensitive unit in a longitudinal direction of the strain sensor;
- an at least one intermediate sensitive unit positioned between the first end sensitive unit and the second end sensitive unit;
- and
- at least one wiring line to connect the first end sensitive unit, the second end sensitive unit, and the at least one intermediate sensitive unit,
- wherein each of the first end sensitive unit, the second end sensitive unit, and the at least one intermediate sensitive unit is an element having a length formed by repeatedly folding a linear resistor in parallel.
