PROBLEM TO BE SOLVED: To repeatedly use a cutting die body by forming the cutting die body out of a nearly basin-like die main body made of a metal sheet and a cover body made of the metal sheet and fitted to the die main body to shield its upper opening. SOLUTION: A drain main body 1 is formed with a pan section 2 and a drain pipe section 3 protruded downward from the lower face of the pan section 2. A cutting die body 7 is mounted on the drain main body 1 and held by a holding means 8. The cutting die body 7 is formed with a nearly basin-like die main body 7a and a cover body 7b removably fitted to the die main body 7a to shield its upper opening, and it is formed into a shape matched with the shape of a drain ditch to be execution-molded by the drawing of a metal sheet. A material such as steel, stainless steel or aluminum is used for the metal sheet forming the die main body 7a and the cover body 7b, therefore the cutting die body 7 has strength and can be used multiple times, and it can be recycled because it is made of metal.
