Claim Text:
1. An ultrasonic device comprising: an ultrasonic element group including a plurality of ultrasonic elements, the ultrasonic elements forming “N” columns arranged along a second direction intersecting with a first direction with each of the “N” columns including a plurality of the ultrasonic elements arranged along the first direction, “N” being a natural number that is equal to or more than 2; a first to an Nth driving electrode lines arranged along the first direction; a first terminal from which a first driving signal for driving the ultrasonic elements, which is an alternating voltage, is supplied to the ultrasonic elements; and a second terminal from which a second driving signal for driving the ultrasonic elements, which is an alternating voltage, is supplied to the ultrasonic elements, an ith driving electrode line among the first to the Nth driving electrode lines being connected to the ultrasonic elements constituting an ith column among the “N” columns, with “i” being a natural number that is equal to or less than “N”, the first terminal being connected to one end of the ith driving electrode line, the second terminal being connected to the other end of the ith driving electrode line.
