PROBLEM TO BE SOLVED: To provide an ultrasonic imaging apparatus capable of efficiently generating an image both by using a transmission ultrasonic wave with a wide directivity angle and by using a transmission ultrasonic wave with a narrow directivity angle. SOLUTION: The ultrasonic imaging apparatus includes: a transmission control part controlling transmission timing of a plurality of first piezoelectric elements so as to make the composite wave of ultrasonic waves transmitted from the plurality of first piezoelectric elements correspond to an ultrasonic wave transmitted from a predetermined virtual transmission point; a signal detecting circuit detecting an electric signal corresponding to an ultrasonic echo transmitted from the plurality of first piezoelectric elements, reflected by an inspection target, and received by a plurality of second piezoelectric elements; and a generating part generating an image corresponding to the inspection target, according to the electric signal.
