| titleOfInvention | Piezoelectric ceramic, piezoelectric element, and method of manufacturing the piezoelectric ceramic |
| abstract | PROBLEM TO BE SOLVED: To provide a piezoelectric ceramic having a small hysteresis of output charge output from the piezoelectric ceramic when a load is applied. [Solution] It has a pair of parallel main surfaces 2a and 2b located on the opposite side of the base 21 and side surfaces 4 connected to the peripheral edges 3a and 3b of the main surfaces 2a and 2b, respectively, and the composition formula is Bi 4 Ti 3 O. 12 · αMTiO 3 as a main component, M is at least one of Sr and Ba and 0.1 ≦ α ≦ 1 in the composition formula, and 0.1 ≦ α ≦ 1 is satisfied. X-ray diffraction using Cu—Kα rays with respect to the side surface 4 of the outer region 22, which includes an outer region 22 including the neighboring regions 4 A and 4 B of the surfaces 2 a and 2 b and an inner region 24 surrounded by the outer region 22. in the half-value width W a of peak diffraction angle (2 [Theta]) is in the range of 22.8 ° ~23.5 ° is, X-rays diffraction using Cu-K [alpha line for each main surface 2a and 2b of the inner region 24 In , To provide a piezoelectric ceramic 20, characterized in that the diffraction angles (2 [Theta]) is smaller than the half-value width W B of a peak in the range of 22.8 ° ~23.5 °. |
