This disclosure provides an ultrasonic cartilage analyzing device, an ultrasonic cartilage analyzing method, and a program that can provide analysis data for quantitatively evaluating an accurate state of a cartilage. An oscillator (11) transmits a pulse burst signal to two or more locations within an attention area of a person's knee, and an echo signal reflected on the cartilage is received by echo signal receiver (12). An echo signal analyzer (13) acquires amplitude values of the received echo signals, and then calculates an average value and a standard deviation of the acquired amplitude values. An analysis data generating module (132) of the echo signal analyzer (13) further calculates a variation coefficient (CV) of the attention area based on the calculated average value and standard deviation of the amplitude values. An analysis data generating module (132) generates the analysis data for the cartilage based on the calculated variation coefficient (CV).
