<P>PROBLEM TO BE SOLVED: To provide a pressure detection part for improving the precision of sensitivity so that accurate information input can be performed by a pressurizing operation in an information input device. <P>SOLUTION: A pressure detection part arranged in the peripheral edge of a panel member in an information input device, and configured to detect a pressurizing operation with respect to the panel member is provided with: a first substrate 21; a second substrate 22 arranged so as to be faced to the first substrate 21; a pressure-sensitive layer arranged between the first substrate 21 and the second substrate 22; and a first electrode 21A formed on the first substrate 21 and a second electrode 22A formed on the second substrate 22 so that a resistance change via the pressure-sensitive layer can be detected. The first electrode 21A and the second electrode 22A are formed at positions where they are not faced to each other on the normal of the first substrate 21 and the second substrate 22, and a loop-shaped series circuit is formed of the first electrode 21A, the second electrode 22A and the pressure-sensitive layer. <P>COPYRIGHT: (C)2012,JPO&INPIT |
