SENSOR UNIT, INPUT DEVICE, AND ELECTRONIC APPARATUS
First Claim
1. A sensor unit comprising:
- a first substrate;
first and second electrodes;
an input portion disposed so that a gap exists between the substrate and the input portion;
a plurality of first structures disposed in the gap and extending at least partially between the first substrate and the input portion; and
a second insulating structure disposed on a side of the first structures that is away from the input portion, or between adjacent first structures;
wherein the sensor unit is configured to detect a change in capacitance between the first and second electrodes upon a change in position of the input portion relative to the first substrate.
