PROBLEM TO BE SOLVED: To provide an inspection device for a casting crude material with a hole, capable of inspecting exactly a surface physical property of the casting crude material with the hole of low dimensional precision before finishing work, conveyed on a conveying line, and capable of detecting exactly a flaw thereof. SOLUTION: An advancing and retracting mechanism 3 is provided to advance and retract a floating device 5 toward/from the casting crude material S with the hole, in an upper part of an inspection zone 1 for stopping the casting crude material S with the hole conveyed on the conveying line 2, a copying mechanism 50 is provided to be engaged with a plurality of molding hole C insides formed on molding upper face of the casting crude material S with the hole and to copy an inclination to an X-/Y-direction on the molding upper face of the casting crude material S with the hole, in the floating device 5, a sensor 4 is attached to the copying mechanism 50, so as to detect the flaw and to inspect the surface physical property, by bringing a plane contact 4a into close contact with the molding upper face of the casting crude material S with the hole, the copying mechanism 50 is inclined thereby to get in parallel to the casting crude material S with the hole in response to the inclination of the molding hole C of the casting crude material S with the hole, and the plane contact 4a of the sensor 4 is brought exactly into close contact with the molding upper face of the casting crude material S with the hole.
