A device for measuring elastic properties, comprising a long bar-like probe base ( 42 ) and probes ( 50 a, 50 c) fitted to the probe base ( 42 ) driven as to be pressed against and withdrawn from a living body tissue. The probes are so formed that generally semi-spherical contact balls ( 58 ) having stress detection bases ( 56 ) are fitted to the ends of leaf strings ( 52 ) and stress detection sensors ( 60 ) are disposed on the stress detection bases ( 56 ). Light-receiving elements are fitted to the opposite side of the leaf displacement sensors ( 62 a, 62 b). The stress sensors ( 60 ) and displacement sensors ( 62 a, 62 b) are connected to the device body through signal lines ( 92, 94 ), respectively. The profile of the displacement of the tissue is calculated and displayed in a manner indicating correlation with stress.
