[Problem] To provide an ultrasonic analyzing device, an ultrasonic analyzing method and an ultrasonic analyzing program for generating analysis data with which to evaluate the state of cartilage quantitatively, in a non-invasive manner. [Solution] This ultrasonic analyzing device is characterized in being provided with: a first echo extracting unit which extracts, from an echo signal received from the interior of an examination subject internally containing cartilage, first echo data relating to a prescribed sector corresponding to a first location of interest relating to the cartilage, the echo signal originating from an ultrasound signal transmitted from the surface of the examination subject to the interior thereof a second echo extracting unit which extracts, from the echo signal, second echo data relating to a prescribed sector corresponding to a second location of interest relating to the cartilage a first feature quantity calculating unit which calculates a first feature quantity relating to the echo signal, from the first echo data extracted by the first echo extracting unit a second feature quantity calculating unit which calculates a second feature quantity relating to the echo signal, from the second echo data extracted by the second echo extracting unit and an analysis data generating unit which generates analysis data indicating the state of the cartilage, on the basis of a difference between the first feature quantity calculated by the first feature quantity calculating unit and the second feature quantity calculated by the second feature quantity calculating unit.Le problème décrit par la présente invention est de fournir un dispositif danalyse ultrasonore, dun procédé danalyse ultrasonore et dun programme danalyse ultrasonore pour générer des données danalyse grâce auxquelles il est possible dévaluer létat dun cartilage quantitativement, de manière non effractive. La solution selon la présente invention porte sur un dispositif danalyse ultrasonore ét
