PROBLEM TO BE SOLVED: To provide a mold for reduced pressure casting having a sealing structure with which the fixing property of a sealing material is excellent and a groove for holding the sealing material is easily formed and molten metal intruded into the groove and solidified can be removed in extremely simple method and exchange of the sealing material can easily be performed. SOLUTION: The mold 1 for reduced pressure casting has the sealing structure, in which the groove 9 for holding the sealing material formed on the mold mating face in a plurality of molds and having non-undercut shape in the cross section, is provided and the sealing material 5 is inserted into the groove 9 for holding the sealing material and also, a groove 11 for holding a fixed member connectively formed in the groove 9 for holding the sealing material and having non-undercut shape in the cross section, is provided and the undercut shaped fixed member 13 is inserted into the end part at the side contacting with the sealing material 5 in the cross sectional shape of the groove 11 for holding the fixed member to fix the sealing material 5 with the fixed member 13.
