PROBLEM TO BE SOLVED: To display an ultrasonic image by tissue by selectively extracting an ultrasonic echo signal generated in an area with different reflection characteristics from ultrasonic echo signals. SOLUTION: The ultrasonic imaging apparatus comprises an ultrasonic probe 100 comprising a plurality of ultrasonic transducers for transmitting ultrasonic waves toward a subject and outputting receiving signals by receiving ultrasonic echo signals propagated from the subject, a reflection signal evaluation part 132 for evaluating the commutative quality of a group of receiving signals for a prescribed region inside the subject among a plurality of receiving signals outputted from the respective ultrasonic transducers, and a variable amplification part 134 for amplifying the group of receiving signals at a signal amplification rate determined for each receiving signal based on the result of evaluation by the reflection signal evaluation part.
