PURPOSE:To improve the cooking property of the grill by providing a lower heat source and an upper heat source and disposing a cleaning material immediately above the lower heat source. CONSTITUTION:An upper part source 11 having a burner port plate 10 of a grill box 9 heats the upper surface part of a material to be cooked. A Bunsen flame formed by the lower heat source 15 heats the inner part of a cleaning material 14 made of porous ceramics, and heats a part of the cleaning material in candescence. Oil parts and water contents leaching from the material to be cooked drop downward. Oil parts which have contacted the cleaning material 14 is subjected to pyrolysis while impregnating into fine holes formed in the inner part of the cleaning material 14, and is sprayed while being decomposed into CO2 and steam. The water content falling onto the cleaning material 14 is sprayed in the form of steam. Further, the cleaning material 14 itself becomes a radiation heat source and the material to be cooked undergoes the heating operation on both upper and lower surfaces.
