To provide a high frequency induction heating melting device for an insulation material capable of continuously melting an insulating material without mechanical agitation only by charging an insulation material in succession.

In the high frequency induction heating melting device for an insulating material, a high frequency induction coil is situated at the outside of a furnace body, and an conductive container formed of a conductive material is situated at the internal part of the furnace body and provided at an upper part with a charge port for an insulation material and at a bottom part with an ejection hole for a molten insulation material. The conductive container is formed with a protrusion upward in the center of the bottom. Since an non- molten insulation material is positioned near the inner peripheral surface of the outer peripheral part of the conductive container, heating is apt to be applied from an inner peripheral surface. Simultaneously with melting, a heat insulation material near the central protrusion part collapses owing to its owing weight and is moved to the inner peripheral side and makes easy contact with the inner peripheral surface side, and continuous melting is carried out.
