Abstract
Disclosed is an ultrasound probe which outputs ultrasound on a basis of a drive signal which is to be received. The ultrasound probe including a composite piezoelectric layer in which a piezoelectric material and a polymer material are arranged alternately in a one-dimensional array or in a two-dimensional array, an acoustic reflection layer which has an acoustic impedance higher than an acoustic impedance of the composite piezoelectric layer and an adhesion layer which bonds the composite piezoelectric layer and the acoustic reflection layer wherein in a bonding surface of the composite piezoelectric layer that bonds with the acoustic reflection layer, a polymer material part is concaved in a direction opposite to an acoustic reflection layer side comparing to an piezoelectric material part.
