PROBLEM TO BE SOLVED: To improve durability in fusion and damage by thermal shock of a porous ceramic filter for diesel exhaust gas. SOLUTION: The ceramic filter for trapping and burning diesel exhaust particulates provides improved structure of which durabilty in cracking by heat and damage by fusion are very high. The ceramic filter comprises a honeycomb filter body 20 made of porous ceramic material, in which plural cell channels parallel to each other and passing through the filter body from an inflow end face 22 to a discharge end face 24 are included, and a part of the cell channels are blocked to form a non-checkered pattern and the remaining cell channels are blocked to form a checkered pattern. The inflow end face of the honeycomb filter body has a checkered pattern blocked section and a non-checkered pattern blocked section. Further, the honeycomb filter body may have a plurality of block plugs in the cell channels, or may have a plurality of partial cell channels that extend up to a predetermined point in the honeycomb filter and are not blocked at the inflow end face.

PROBLEM TO BE SOLVED: To provide a fuel cell electrolyte sheet with a surface uneven pattern having an allowable distortion of 0.5% or higher in whatever direction of sheet surface. SOLUTION: An unfired flexible ceramic sheet containing a ceramic powder and a thermoplastic organic binder is formed, and at least a portion of the unfired ceramic sheet is heated to soften the binder to form a thermally softened sheet. The softened sheet is reformed to form a pleated sheet, having a sheet uneven array forming multidirectional surface pleats on at least a portion of the sheet. The pleated sheet is fired to remove the binder and sinter the ceramic powder to form a flexible ceramic sheet with the multidirectional surface pleats.
