| 摘要 |
The present invention provides a structure including a surface coat layer of which the thickness on a bump such as a weld bead and a weld spatter or an edge portion, possibly formed on the surface of a base, is not greatly different from the thickness on a flat portion. The structure therefore has excellent properties including heat insulation properties and electrical insulation properties. The structure includes a base that is made of a metal, and has a flat portion and at least one of a bump and an edge portion on a surface; and a surface coat layer that covers the surface of the base, the surface coat layer including: a first surface coat layer that covers the flat portion, and contains an amorphous inorganic material, or a crystalline inorganic material and an amorphous inorganic material in combination; and a second surface coat layer that covers the at least one of a bump and an edge portion, and contains the crystalline inorganic material and the amorphous inorganic material, the second surface coat layer containing a higher percentage by weight of the crystalline inorganic material than does the first surface coat layer. |
