PROBLEM TO BE SOLVED: To provide a snow melting panel and a snow melting device which are laid on the upper surface of the eaves of a metal roof surface at all times to secure an electrically insulated condition even if exposed to the turbulence such as snow, rain and a storm, and heat, while following the thermal deformation of the metal roof plate to melt a layer of snow on the upper surface of the eaves to prevent the formation of ice bars and icicles. SOLUTION: An upper far-infrared ray generator 3 under a layer of snow and a lower far-infrared ray generator 4 joined to the upper surface of the eaves of the metal roof surface wrap a surface heating sheet 2 in a watertight condition. A front joint plate 11 joined to the upper surface of the longitudinal front part of the upper far-infrared ray generator 3 is joined to the metal roof surface. A rear joint plate 12 joined to the upper surface of the rear of the generator 3 is joined to a cable duct 17 attached to a fascia board 16 at the eaves. A cable 18 connected to a power supply is passed through the cable duct 17, and lead wires 7, 8 extending from each snow melting panel (a) in a watertight condition are connected thereto. The snow melting device A is laid on the upper surface of the eaves of the metal roof surface. COPYRIGHT: (C)2004,JPO
