1. A sensor device comprising:
- a pressure-sensitive sensor including an elastic body aligned with and sandwiched between upper and lower electrodes and configured to change shape in response to pressing of an operation tool so as to detect change in capacitance due to the change in shape; and
a barrier which covers a substantial periphery of multiple planar sides of the pressure-sensitive sensor and placed against respective surfaces of the multiple planar sides, the barrier being made from a conductive material and electrically grounded,wherein the change in capacitance detected by the pressure-sensitive sensor is caused by a change in a distance between the upper and lower electrodes due to the pressing of the operation tool, andwherein the upper and lower electrodes and the elastic body of the pressure-sensitive sensor are all aligned in a stacked configuration in a stacking direction, and the upper and lower electrodes are arranged in substantially similar configurations in their respective layers.

Abstract
A sensor device is provided which includes a pressure-sensitive sensor which changes shape in response to pressing of an operation tool and which detects change in capacitance due to the change in shape, and a barrier which covers at least a part of the pressure-sensitive sensor and which prevents change in capacitance of the pressure-sensitive sensor due to capacitive coupling that occurs with approach between the pressure-sensitive sensor and the operation tool.
