There is provided an ultrasonic imaging apparatus capable of efficiently generating an image both by using a transmission ultrasonic wave with a wide angle of beam spread and by using a transmission ultrasonic wave with a narrow angle of beam spread. The ultrasonic imaging apparatus includes: a transmission control part controlling transmission timings of a plurality of first piezoelectric elements so as to make a synthesized wave of ultrasonic waves transmitted from the plural first piezoelectric elements match 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 plural 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 based on the electric signal.
