PROBLEM TO BE SOLVED: To provide a molding for forming a ceramic resistance heating element, having large-diameter linear parts and a small-diameter linear part by itself, and capable of being manufactured by injection molding, and remarkably thinning the small-diameter linear part in comparison with a conventional one without lowering a yield rate in manufacturing the molding. SOLUTION: The molding 1 itself has the U-shape, a straight portion 3a near a tip including a folded part 2 of the U-shape is composed of the small-diameter linear part 3, and both leg parts 4 of the U-shape are composed of the large-diameter linear parts 5. A projecting part 9 is formed on a proper place of the small-diameter linear part 3 in a state that a projecting pin for projecting the molding 1 itself from a molding die after injection molding, can be projected from the small-diameter linear part 3 with proper places P1-P5 of the large-diameter linear part 5.
