A pressure detection unit 20 is disposed in a peripheral portion 4A of a panel member 4 of an information input device in order to detect a press operation to the panel member 4. The pressure detection unit 20 includes a first substrate 21, a second substrate 22 disposed to face the first substrate 21, pressure sensitive layers 23a, 23b disposed between the first substrate 21 and the second substrate 22 and a first electrode 21A provided on the first substrate 21 and a second electrode 22A provided on the second substrate 22 for detecting resistance change via the pressure sensitive layers 23a, 23b, respectively, the first electrode 21A and the second electrode 22A being provided at positions not facing each other on normal lines of the first substrate 21 and the second substrate 22. |
