PROBLEM TO BE SOLVED: To solve a problem wherein a flexible printed circuit board is joined to an Si substrate and the Si substrate is required to be worked, to require thereby a complicated process, since manufactured using the Si substrate in conventional constitution. SOLUTION: This pressure sensor device 11 of the present invention is easy to manufacture, because constituted of an organic FET on the flexible printed circuit board. In concretely saying, the organic FET is constituted of an organic semiconductor layer 2, an insulating layer 5, a gate 6, a drain 3 and a source 4, the organic semiconductor layer 2 is formed of aπ-conjugated polymer, the insulating layer 5 is formed of an organic insulating material, and a piezoelectric material of a piezoelectric polymer layer 7 is connected electrically to the gate 6.
