Abstract
A pressure detection unit is disposed in a peripheral portion of a panel member of an information input device in order to detect a press operation to the panel member. The pressure detection unit includes a first substrate, a second substrate disposed to face the first substrate, pressure sensitive layers disposed between the first substrate and the second substrate and a first electrode provided on the first substrate and a second electrode provided on the second substrate for detecting resistance change via the pressure sensitive layers, respectively, the first electrode and the second electrode being provided at positions not facing each other on normal lines of the first substrate and the second substrate.
