1. An ultrasonic transducer comprising:
a plurality of vibrators; and
a connection portion connecting the vibrators to each other, wherein
each of the vibrators has a piezoelectric element and a vibration plate joined to the piezoelectric element,
the connection portion connects the vibration plates to each other,
a width W2 of the connection portion is smaller than a width W1 of the vibration plate,
the width W1 of the vibration plate refers to a maximum length thereof in a direction orthogonal to a thickness direction of the vibration plate, and
the width W2 of the connection portion refers to a largest width of the connection portion thereof in a direction orthogonal to a thickness direction of the connection portion.
