<p>Disclosed are a transducer which can measure a physical property even in a sample having a size smaller than 1 mm and a measuring instrument. A transducer comprising a cylindrical casing having a film-like electrode attached on one end terminus, a film-like piezoelectric substance provided on the side wall of the electrode which faces to the inner wall of the casing, a conductive wire inserted into the casing with a concentric configuration so as to be connected to the piezoelectric substance, and an insulating material filled in the interior of the casing, the piezoelectric substance comprising at least one substance selected from quartz, barium titanate, lead titanate, lead zirconium titanate, lead lanthanum zirconium titanate, lithium niobate, lead methaniobate, Roschell salt, ethylenediamine tartrate, potassium tartrate, dibasic ammonium phosphate, tungsten bronze crystal, lithium tantalate, poly(vinylidene fluoride) and zinc oxide and having a thickness of 0.1 mm or less.</p> |
