In an ultrasound probe (2) and a method for manufacturing the ultrasound probe (2) of the invention, an organic piezoelectric element (21) has a sheet-like form, and is directly or indirectly laminated on a part or the entirety of a plurality of inorganic piezoelectric elements (22). Accordingly, the ultrasound probe (2) can be manufactured with a less number of steps. An ultrasound diagnostic apparatus of the invention includes the ultrasound probe (2). Accordingly, the cost of the ultrasound diagnostic apparatus can be reduced.
