PURPOSE:To obtain an element, which can measure only pushing force and has rectifying action, excellent strength and high sensitivity, by forming electrode films on both surfaces of a high-molecular piezoelectric film and bonding a tabular body consisting of a rubbery elastic material on one surface or both surfaces of the electrode films. CONSTITUTION:Electrode films 2a, 2b are formed on both surfaces of a high- molecular piezoelectric film 1 in which a composition, wherein a 60wt.pts. polyacetal resin and a 40wt.pts. acrylonitrile-butadiene rubber are kneaded, and titanic acid-zinc zirconic acid powder are kneaded at the rate of equal capacity, molded in 100mum thickness and polarized, and a tabular body 3a consisting of an silicone rubber, etc. is bonded onto the electrode film 2a, or elastic tabular bodies 3a, 3b are bonded onto the electrode films 2a, 2b. Accordingly, an element, which can measure only pushing force and has rectifying action and excellent strength, is obtained. |
