A molding device for continuous casting with a stirring unit that suppresses the amount of generated heat, requires easy maintenance, and is easy to use actually, is provided as a molding device that can be made small at a low cost regardless of the size of a product to be obtained. The molding device includes 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. 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 of the transition plate body with the bottom plate interposed therebetween and making lines of magnetic force vertically run into the casting space, and a pair of electrodes including a first electrode provided at the inlet side and a second electrode provided at the outlet side.
