An object of the present invention is to provide a tool measuring device and a tool measuring method. The offset amount in the distance between each outer surface of the protrusion and the rotation axis can be knew when a plurality of protrusions are compared in a rotating tool. The solution of the present invention is to provide a tool measuring device (1) comprising a camera (22), a spindle rotation angle sensor (23), and a control device (20). The tool (12) at least has an operating part (46) including two protrusions (48) that is a first protrusion (481) and a second protrusion (482). The control device (20) has an imaging command control part (25) and a calculation part (27). The imaging command control part (25) outputs an imaging command to the camera (22) in a plurality of phases with different rotation angles of a spindle (11). The calculation part (27) calculates the first distance and the first phase at this moment and the second distance and the second phase at this moment according to a plurality
