PROBLEM TO BE SOLVED: To provide a novel metal mold for blow molding capable of arranging a stopper mechanism in a laminated plate having a door , the laminated plate manufactured by using the same, and a manufacturing method of the laminated plate. SOLUTION: The laminated plate is formed by blow molding by injecting compressed air by welding mutual ends of two thermoplastic resin plates 6 and 7, and has a body 4M and the door 5 forming an upper side integral hinge 8 as a cut and raised base BL by cutting and raising a part of the body 4M in a predetermined shape. In the blow molding, the door 5 is formed in a state of being inclined to the body 4M, and a distance to a cut and raised tip 5S from the upper side integral hinge 8 is elongated longer than a distance to the inside edge 4E of the body 4M from the upper side integral hinge 8, and the cut and raised tip 5S is overlapped by a predetermined quantity (d) with the inside edge 4E of the body part 4M.
