PROBLEM TO BE SOLVED: To measure elastic modulus of a cell by a micro-manipulator. SOLUTION: This micro-manipulator has an operating needle 14 to be controlled under a visual field of a microscope, and a force sensor 17 holding the operating needle 14. Further, the micro-manipulator is provided with an operation part 10 to input operation factors such as a moving direction, a moving length, a moving speed, etc., of the operating needle and to output an operation instruction signal according to the inputted operation factors, X-, Y-, and Z-control circuits 11 and X-, Y-, and Z-stages 12, a holder 13 which receives kinetic energy from the X-, Y-, and Z-stages 12 and geometrically displace the operating needle 14, a sensor 17 to detect a force acting on the operating needle 14, and a converter 18 and a force calculation circuit 19. Thus, an elastic modulus of an organism sample 15 such as cells is detected.
