A method for manufacturing a porous ceramic structure which can produce a
high porosity ceramic structure as well as a low porosity ceramic
structure without causing cracks at the time of firing. A method for
manufacturing a porous ceramic structure comprising molding a raw
material which contains a ceramic material as a main component and a
pore-forming agent and then drying and firing the obtained molded
article. When the molded article is fired, the temperature of a firing
environment is raised substantially in synchronization with the
temperature of the central portion of the molded article within a
temperature range in which at least a portion of the molded article is
shrunk by firing.
