Patent number: 7001014Abstract: A piezoelectric thin film can achieve a large piezoelectric displacement. A chemical composition of the piezoelectric thin film is expressed by Pb1+a(ZrxTi1?x)O3+a(0.2?a?0.6 and 0.50?x?0.62). The crystal structure of the piezoelectric thin film is a mixture of a perovskite columnar crystal region (24) having an ionic defect in which a portion of the constitutive elements of an oxygen ion, a titanium ion, and a zirconium ion is missing and a perovskite columnar crystal region (25) of stoichiometric composition having no ionic defect. This configuration allows a residual compressive stress in the crystal to be relaxed by the perovskite columnar crystal region (24) having an ionic defect, thus achieving a large piezoelectric displacement (displacement amount).Type: GrantFiled: September 26, 2001Date of Patent: February 21, 2006Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Hideo Torii, Takeshi Kamada, Isaku Kanno, Ryoichi Takayama
