To provide a tabular structure suitable as a setter for baking providing compatibility between degreasing and surface smoothness of a burned product, and its manufacturing method.
Since a ventilation passage 32 communicated with an outer circumference is formed by protrudedly providing a columnar protrusion 16 on one face of a porous tabular part 12 provided with minute communication pores, a passage for air passing through the tabular part 12 from its another face to a one face side in a thickness direction and reaching the outer circumference via the ventilation passage 32 is formed in the setter 10 for baking. Thereby, despite the flatness of the other face mounted with a sheet like forming body 28, degreasing gas is suitably exhausted, and uniformity of temperature distribution can be enhanced. In other words, compatibility between degreasing and surface smoothness can be provided.
