Abstract
A method for producing a sintered body includes: a) molding a composition containing a powder primarily made of an inorganic material and a binder including an aliphatic carbonic acid ester based resin in a predetermined shape so as to obtain a compact; b) exposing the compact to a first atmosphere containing an alkaline gas and thus decomposing and removing the aliphatic carbonic acid ester based resin from the compact so as to obtain a degreased body; and c) sintering the degreased body so as to obtain a sintered body.
