Summary:PROBLEM TO BE SOLVED: To make it possible to efficiently set a gas-permeable sheet to be arranged along the lower face of a top form to be installed on the upper part of a bottom form and, make the gas-permeable sheet easily detachable. SOLUTION: This shuttering 11 for a concrete product consists of a bottom form 12 with a lateral form part 15 provided on the periphery of a bottom plate part, a top form 13 which is set on the upper part of the bottom form 12 and has the lower face side recessed upward forming a curved face 13a, and a gas-permeable sheet 17 which is arranged along the curved face 13a of the top form 13 and removes a bubble generated above a formed concrete. In addition, fitting piece parts 19 are formed on the curved face 13a near both end parts in the longitudinal direction of the top form 13. Further, the gas- permeable sheet 17 is arranged along the curved face 13a of the top form 13. Both end parts of the long band-like elastic support plate 18 are arranged along the curved face 13a of the top form 13 by fitting the end parts into the fitting piece parts 19 respectively. Next, the gas-permeable sheet 17 is supported by holding it between the curved face 13a and the support plate 18, and then is arranged along the lower face 13a of the top form 13.
