Abstract
A pressure detection unit includes a first substrate and a second substrate which are disposed in opposition to each other and subject to load from the outside, a pressure detection portion having a pair of electrodes provided between the first substrate and the second substrate and in the first substrate and the second substrate, and electrically conductive pressure-sensitive ink disposed between the pair of electrodes and having electrical characteristics which varies according to the load, and a load transmission member disposed between the first substrate and the pressure detection portion and/or between the second substrate and the pressure detection portion, the load transmission member transmitting the load to the pressure detection portion in a concentrated manner.
