<P>PROBLEM TO BE SOLVED: To provide an electrical insulating cast article including an adhesive interface having an excellent high-temperature creep property for a long time without deteriorating the adhesive force thereof even if a cast operation is performed after it is retained for a long period after an anodizing treatment, and to provide a method of manufacturing the electrical insulating cast article including such an adhesive interface. <P>SOLUTION: An oxide film 16 is made up of plural prismatic cells 8. A hole 3 extending in an axial direction of the prismatic cell and opening at a surface of the prismatic cell is formed approximately in the vicinity of a center of the prismatic cell 8, and branch holes 7 extending approximately in a vertical direction relative to an inner peripheral surface in an axial direction of the hole 3 are further formed at the inner peripheral surface. A thickness of the oxide film is thicker than 0.5 μm and less than 2.0 μm. An adhesive is filled into each hole of the prismatic cell and of which thickness is 1 μm or more and 40 μm or less. <P>COPYRIGHT: (C)2013,JPO&INPIT |
