PROBLEM TO BE SOLVED: To provide a behavior/physical strength evaluation apparatus, behavior/physical strength evaluation method, and program capable of further simply and highly accurately estimating behavior and physical strength.SOLUTION: A behavior/physical strength evaluation apparatus 100 includes an estimation part for estimating values related to behavior/physical strength on the basis of at least one selected from a group of a capacitance, a reactance, a characteristic frequency, and a phase angle of a membrane obtained by a bioelectric impedance method. The values related to the behavior/physical strength may be at least one selected from a group consisting of muscle power, muscle strength, a walking speed, an ability of rising from a chair, an ability of climbing up/down stairs, and maximum oxygen intake.SELECTED DRAWING: Figure 3
