An ultrasonic diagnosis apparatus includes: a frequency analyzing unit that calculates a frequency spectrum of a received ultrasonic wave a frequency band setting unit that sets at least an upper limit frequency for use in approximating the calculated frequency spectrum to a predetermined frequency according to a receiving depth of an ultrasonic wave a feature data extracting unit that extracts feature data of the frequency spectrum by approximating a frequency spectrum of the frequency band a storage unit that stores feature data of a frequency spectrum extracted based on ultrasonic waves reflected off known specimens in association with tissue characteristics of the known specimens and a tissue characteristic determining unit that determines a tissue characteristic in a predetermined area in the specimen using feature data stored in the storage unit in association with tissue characteristics of the known specimens and the feature data extracted at the feature data extracting unit.
