<P>PROBLEM TO BE SOLVED: To provide a pressure sensor where resistance value continuously changes as pressure changes. <P>SOLUTION: The pressure sensor 1 is provided with: a pressure-sensitive film 2 where resistance value changes according to pressure; a pair of electrodes 3 which grip the pressure-sensitive film 2; and a flexible film 4 which is pasted on one of the electrodes 3 so that one of the pair of electrodes 3 approximates to the other. In the pressure sensor 1, the pair of electrodes 3 compress the pressure-sensitive film 2. The pressure sensor 1 is also provided with a base film 5 having an opening part 5a which goes through in the thickness direction. In the pressure sensor 1, the pressure-sensitive film 2 is provided at the opening part 5a of the base film 5 by matching thickness directions of the base film 5 and the pressure-sensitive film 2. A step part 11 is composed by the base film 5 and one of the electrodes 3. The flexible film 4 is pasted from the base film 5 to one of the electrodes 3 in the way that it goes along with the step part 11. <P>COPYRIGHT: (C)2013,JPO&INPIT |
