PROBLEM TO BE SOLVED: To provide a form which has a high tenacity and is excellent in expansion-resistance and vibration-resistance. SOLUTION: For this form, a hydraulic paste containing at least a hydraulic material, a reinforcing fiber and water is used. In this case, at least one section of the reinforcing fiber is a polyvinyl alcohol based fiber wherein the size is 8 to 270 dtex, and the strength is 4 cN/dtex or higher. Also, the compression strength of a standard molded body obtained from the hydraulic paste is 45 to 120 MPa, and the bending strength of the standard molded body is 12 MPa or higher for the form.
