To provide a heating structure and heating method for a molten metal vessel that can prevent a reduction in thermal efficiency by efficiently burning solid fuel at a regenerative burner.

The regenerative burner 14 is disposed on a lid 12 for closing a top opening of a ladle 10, and liquid fuel supplied to the regenerative burner 14 is burned to heat the interior of the ladle 10. In a position of the lid 12 spaced from the regenerative burner 14, a solid fuel supply pipe 18 is disposed to supply solid fuel SF to the burner flame F of the regenerative burner 14.
