A material having an internal cooling passage is provided which reduces a recirculation area to perform effective cooling. In the internal cooling passage formed in the material there is a wall surface provided with cooling ribs thereon to allow a cooling medium to flow along the wall surface, and the cooling ribs are arranged so that a portion of the cooling medium flowing in the vicinity of the center of the wall surface included in the cooling passage is allowed to flow toward both side edges of the wall surface and so that a portion of the cooling medium flowing on a surface of the cooling ribs moves to conform to the surface of the cooling ribs and flows to the wall surface.
