PURPOSE: A curved surface measuring method is provided to measure the curvature and concentricity of a curved surface using a curved surface measuring apparatus including a main body, a rotating member, and a measuring unit which are in contact with each other. CONSTITUTION: A curved surface measuring method comprises a step(S100) of setting a curved surface measuring device on an object having a curved surface, wherein the curved surface measuring device includes a rotating member installed on a main body, a fastening member connecting the main body and the rotating member, and a measuring unit which is installed on one side of the rotating member and controlled in length, and a step(S300) of measuring the curvature of the object by rotating the measuring unit around the center of the fastening member and the concentricity of the object by rotating the main body, wherein the bottom surface is in contact with one side of the object.
