摘要
Provided is a piezoelectric substrate including: an elongate conductor; and an elongate first piezoelectric material helically wound in one direction around the conductor, in which the first piezoelectric material includes an optically active helical chiral polymer (A), the lengthwise direction of the first piezoelectric material and the principal orientation direction of the helical chiral polymer (A) included in the first piezoelectric material are substantially parallel to each other, and the first piezoelectric material has an orientation degree of F in a range of from 0.5 to less than 1.0, determined from X-ray diffraction measurement by the following Formula (a): orientation degree F = 180 ° ˆ’ ± / 180 ° (in Formula (a), ± represents a half width of a peak derived from orientation).
