PROBLEM TO BE SOLVED: To provide a contact force measuring method and a contact force measuring device of a pantograph capable of performing accurate contact force measurement without installing a sensor on a pressurization part. SOLUTION: A relative displacement of a slider body 110 to a pantograph head 120 is determined based on an imaging result acquired by imaging them by a line CCD camera 150, and the relative displacement is second order differentiated, to thereby calculate a relative acceleration of the slider body 110 to the pantograph head 120. The contact force F of the pantograph 100 is determined by adding an inertia force F<SB>i</SB>of the slider body 110 determined based on the relative acceleration to a reaction force F<SB>r</SB>of a slider body energizing spring 112 determined based on the relative displacement.
