Zusammenfassung:	Provided is a technology in which the relative positional relationship among vibrators is easily stabilized. An ultrasonic transducer (1) includes: a plurality of vibrators (11); and a connection portion (30) connecting the vibrators (11) to each other. Each of the vibrators (11) has a piezoelectric element (21) and a vibration plate (20) joined to the piezoelectric element (21). The connection portion (30) connects the vibration plates (20) to each other. A width (W2) of the connection portion (30) is smaller than a width (W1) of the vibration plate (20). In this configuration, the relative positional relationship among the vibrators (11) is easily stabilized.
