摘要

A side lobe in a capacitive transducer is reduced. Provided is a capacitive transducer including an element including a plurality of cells supported such that a vibrating membrane including one of a pair of electrodes formed with an gap inbetween is capable of vibration, wherein a distance between cells in an end portion of the element is greater than a distance between cells in a middle portion of the element.
