A muscle hardness meter according to the present invention, which measures the hardness of muscle tissue of a living organism, includes: an auxiliary part which touches a periphery of a section of the living organism to be measure so as to apply pressure to the periphery a touching part which touches the section to be measured so as to apply pressure to the section to be measured a first pressure sensor which measures pressures that the touching part and the auxiliary part sustain, respectively, from the section to be measured and the periphery, and outputs a first measurement result a second pressure sensor which measures a pressure that the touching part sustains from the section to be measure, and outputs a second measurement result a notification part which notifies the second measurement result and a control part which determines whether or not the first measurement result teaches a reference pressure value input in advance and notifies the second measurement result to the notification part at a time when it is determined that the first measurement result reaches the reference value.
