To provide a ceramic grating body that can use repeatedly in the high temperature region, and has sufficient strength even when lowering heat capacity by thinning the thickness or when increasing its air permeability.SOLUTION: A ceramic grating body (1) includes plural ceramic-made first linear parts (10) extended toward one direction and plural ceramic-made second linear parts (20) extended toward the direction intersected with the one direction. The grating body (1) includes a first surface (1a) and a second surface (1b) located at the opposite side to the first surface. At the intersections of the first linear parts (10) and the second linear parts (20), the second linear parts (20) located relatively at the second surface (1b) side are arranged on the first linear parts (10) located relatively at the first surface (1a) side. The grating body (1) has surface roughness Ra at the first surface (1a) side of 10 μm or more and 300 μm or less and surface roughness Ra at the second surface (1b) side of 0.01 μm or more and 20 μm or less.SELECTED DRAWING: Figure 1
【課題】高温領域で繰り返し使用でき、且つ、厚みを薄くして熱容量を低くし、また通気性を高めても、充分な強度を有するセラミックス格子体を提供すること。【解決手段】セラミックス格子体（１）は、一方向に向けて延びるセラミックス製の複数の第１の線条部（１０）と、これと交差する方向に向けて延びるセラミックス製の複数の第２線条部（２０）とを有する。格子体（１）は、第１面（１ａ）、及びそれと反対側に位置する第２面（１ｂ）とを有する。第１の線条部（１０）と第２の線条部（２０）との交点においては、相対的に第１面（１ａ）側に位置する第１の線条部（１０）上に、相対的に第２面（１ｂ）側に位置する第２の線条部（２０）が配されている。格子体（１）は、第１面（１ａ）側における表面粗さＲａが１０μｍ以上３００μｍ以下であり、第２面（１ｂ）側における表面粗さＲａが０．０１μｍ以上２０μｍ以下である。【選択図】図１
