Abstract: A heating structure includes: an object to be heated that has recesses on the surface thereof; a laminate-type heater that includes a heat-generating layer and a layer covering the same; and a filler that has flexibility and higher thermal conductivity than air, and is inserted into the recesses between the surface of the object and the surface of the laminate-type heater.

Abstract: A sheet-like heater is provided that can be heated quickly and demonstrates excellent heat uniformity, with the wires of the sheet-like heater being insusceptible to breaking. The sheet-like heater has a layered structure and includes: a sheet-like base; a first resin layer that is attached to a principal face of the sheet-like base and comprises a first resin agent; a mixed layer A that is connected to the first resin layer and comprises a mixture of the first resin agent and metallic fibers; a metallic fiber layer that is connected to the mixed layer A, consists only of metallic fibers, and contains air therein; a mixed layer B that is connected to the metallic fiber layer and comprises a mixture of metallic fibers and a second resin agent; and a second resin layer that is connected to the mixed layer B and comprises the second resin agent.

Abstract: One object of the present invention is to provide a metal fiber nonwoven fabric having high homogeneity, and the present invention provides a metal fiber nonwoven fabric in which metal fibers are bonded to each other having a coefficient of variation (CV value) of a basis weight in accordance with JIS Z 8101 (ISO 3534: 2006) per 1 cm2 of 10% or less.
