An object hardness measuring device includes a first side portion, a second side portion, a pedestal unit, a load unit, a measuring unit, and a holding unit. The load unit applies a load to the measurement object. The measuring unit is able to measure, in a state where the load acts on the measurement object, at least one of a movement distance of the second side portion with respect to the first side portion and a change amount of the load when the second side portion is moved either at a predetermined speed or to a predetermined position. The holding unit is able to hold the measurement object, and is movable between the first side portion and the second side portion by the slide rail unit.
