A molding device for continuous casting with a stirring unit, the molding device from which a solid-phase casting can be taken out by the cooling of liquid-phase melt of a conductive material, the molding device comprising: a mold that forms a casting by cooling the received melt; and a stirring unit that applies a magnetic field to the melt present in the mold and allows a current to flow in the melt in this state, wherein the mold includes a cylindrical mold body that is vertically provided, a central portion of the mold body forms a vertical casting space that includes an upper inlet into which the melt flows and a lower outlet from which a product is taken out, a transition plate body, which has a ring shape and functions as a transition plate, is disposed at the inlet of the mold space, the melt is allowed to flow into the casting space from a hole that is formed at a central portion of the transition plate body, and the stirring unit includes a magnetic field unit including - an upper magnet that includes a permanent magnet body provided above a bottom plate (3A0) of the transition plate body with the bottom plate (3A0) interposed therebetween and making lines of magnetic force vertically run into the casting space, and - a pair of electrodes (5a,5b) that allow the current to flow through the melt when the melt is contained in the casting space, generate an electromagnetic force by making the flowing current cross the lines of magnetic force, and include a first electrode provided at the inlet side and a second electrode provided at the outlet side. a mold that forms a casting by cooling the received melt; and a stirring unit that applies a magnetic field to the melt present in the mold and allows a current to flow in the melt in this state, wherein the mold includes a cylindrical mold body that is vertically provided, a central portion of the mold body forms a vertical casting space that includes an upper inlet into which the melt flows and a lower outlet from which a product is taken out, a transition plate body, which has a ring shape and functions as a transition plate, is disposed at the inlet of the mold space, the melt is allowed to flow into the casting space from a hole that is formed at a central portion of the transition plate body, and the stirring unit includes a magnetic field unit including - an upper magnet that includes a permanent magnet body provided above a bottom plate (3A0) of the transition plate body with the bottom plate (3A0) interposed therebetween and making lines of magnetic force vertically run into the casting space, and - a pair of electrodes (5a,5b) that allow the current to flow through the melt when the melt is contained in the casting space, generate an electromagnetic force by making the flowing current cross the lines of magnetic force, and include a first electrode provided at the inlet side and a second electrode provided at the outlet side. - an upper magnet that includes a permanent magnet body provided above a bottom plate (3A0) of the transition plate body with the bottom plate (3A0) interposed therebetween and making lines of magnetic force vertically run into the casting space, and - a pair of electrodes (5a,5b) that allow the current to flow through the melt when the melt is contained in the casting space, generate an electromagnetic force by making the flowing current cross the lines of magnetic force, and include a first electrode provided at the inlet side and a second electrode provided at the outlet side.
