A diecast machine comprises: a sleeve extending in the vertical direction; a plunger moving upward in the vertical direction inside the sleeve; a mold disposed above an upper side of the sleeve; a case member constituted of a nonconductive member, which covers at least a lower end of the sleeve and forms a closed space including the lower end of the sleeve; a communicating pipe connecting the inside of the closed space to the outside of the closed space; and high-frequency induction coil configured to heat metal material disposed on the plunger from the outside of the case member and melt the metal material.
