To provide a muscle force estimation device and a muscle force estimation method capable of estimating muscle forces of individual muscle groups classified by function in a lower thigh part.SOLUTION: The muscle force estimation device causes a subject to exert end forces in four directions in a two-dimension plane, and measures the end forces exerted in the respective directions by a detection unit. The end force exerting position is estimated based on the measured end force and the moment around the z-axis orthogonal to the two-dimension plane detected by the detection unit when the end force is measured. Each measured end force is converted into a joint torque based on the estimated end force exerting position. On the basis of the converted joint torque, the output distribution of the hexagonal joint torque in which the lengths of all opposite sides are equal is plotted on a torque plane with the joint torque relating to the knee joint as one axis and the joint torque relating to the foot joint as the other axis perpendicular to the one axis. Based on the output distribution drawn by the drawing unit, the muscle group torque of each muscle group of the crus is estimated.SELECTED DRAWING: Figure 5
