To obtain a piezoelectric film having excellent piezoelectric properties. An aspect of the present invention is a piezoelectric film having a crystal oriented in the c-axis direction and a crystal oriented in the a-axis direction, in which, when denoting the amount of a (004) component of the crystal oriented in the c-axis direction by C and denoting the amount of a (400) component of the crystal oriented in the a-axis direction by A, the piezoelectric film satisfies a formula 1 below. C/(A+C)≧0.1  formula 1
