PROBLEM TO BE SOLVED: To provide a form for a gutter reducing operators' labor for the work of removing the form from cured mortar, and making a pair of damaged separated pieces repairable on site, for solving the problems of conventional forms for veranda side gutters: that conventional ones require heavy labor on the part of operators because they are installed through the process of heating a thermally contracting form releasing material in a heating furnace to mount the releasing material to a wooden core having a vertical cross section in the form of an inverted trapezoid, and then attaching specially designed end fittings to their end faces, and also because they are removed through the process of boring holes in the end fittings and inserting bars therein to remove the forms from cured concrete; and the form releasing material is not reusable if damaged during the removal. SOLUTION: The form for a gutter includes a bar-shaped form body 1; a through-hole 2 penetrating the form body 1 from its upper to lower sides and having a threaded groove in at least a portion thereof; and a bolt 5 to be threadedly inserted into the through-hole 2 and being longer than the through- hole 2 so that its tip can move into and out of the lower end of the through-hole 2.
