Abstract
An ultrasonic device includes a first element row in which ultrasonic transducer elements are arranged at line-symmetrical positions along a first straight line, where a second straight line orthogonal to the first straight line is the axis of symmetry, and are connected to a first interconnect, and a second element row in which ultrasonic transducer elements are arranged at line-symmetrical positions adjacent to the first element row, where the second straight line is the axis of symmetry, and are connected to a second interconnect. When the distance between a k-th element included in the first element row and a k-th element included in the second element row is represented by D, a relationship D<Dis satisfied with respect to at least one value of 'k'.
