PCT No. PCT/FR94/00031 Sec. 371 Date Jul. 31, 1995 Sec. 102(e) Date Jul. 31, 1995 PCT Filed Jan. 11, 1994 PCT Pub. No. WO94/17562 PCT Pub. Date Aug. 4, 1994The invention relates to a process for manufacturing a piezoelectric component and to the component resulting from such a process. According to the invention, the manufacturing process comprises the stacking of at least one piezoelectric element (1) and of at least two metallic electrodes (2), each piezoelectric element (1) being inserted between two metallic electrodes (2), characterized in that each piezoelectric element and each metallic electrode is produced, respectively, by coiling a piezoelectric film and by coiling a metallized film.
