Abstract
An ultrasonic device includes an ultrasonic element group, a first to an Nth driving electrode lines, first and second terminals. The ultrasonic element group includes a plurality of 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. The first to the Nth driving electrode lines are arranged along the first direction. An ith driving electrode line is connected to the ultrasonic elements constituting an ith column among the “N” columns, with “i” being a natural number equal to or less than “N”. The first terminal is connected to one end of the ith driving electrode line, and the second terminal is connected to the other end of the ith driving electrode line.
