PROBLEM TO BE SOLVED: To provide a ceramic wiring board including a through hole penetrating the surface and a mounting surface opposing the surface, or a recess opening to the mounting surface, having no micro irregularities on the mounting surface, and capable of keeping a stable posture even if the mounting surface is brought into surface contact with the surface of a surface plate, or the like, and to provide a method of manufacturing the same.SOLUTION: In a ceramic wiring board 1a including a board body 2a laminating a plurality of ceramic layers s1-s3, and having a surface 3 and a mounting surface 4 opposing the surface 3, and a through hole 5 penetrating between the surface 3 and mounting surface 4 in the board body 2a, an inclined plane 10 is formed along the mounting surface 4 surrounding the opening of the through hole 5, and the inclined plane 10 is inclining downward toward the surface 3 side.SELECTED DRAWING: Figure 1 |
