Claim 4:
5. An inspection method for inspecting a core obtained by baking, comprising:
detecting, with a color sensor, a measured value of each color component of a color of a surface of the obtained baked core;
comparing the measured value of at least one color component detected by the color sensor with a threshold prepared corresponding to the at least one color component, thereby determining if a strength property of the obtained baked core is acceptable or not;
measuring, with a distance sensor, a distance between the obtained baked core and the color sensor; and
moving at least one of the obtained baked core or the color sensor based on a measurement result of the distance sensor so that the distance between the obtained baked core and the color sensor reaches a target distance.
