Abstract

A porous sintered body is composed of a perovskite-type composite oxide, wherein A-site of the composite oxide are occupied by one or more kinds of first metallic elements selected from the group consisting of calcium and strontium, one or more kinds of second metal elements selected from the group consisting of rare earth elements and yttrium excluding lanthanum and cerium, and lanthanum, the above one or more kinds of the first metallic elements amount to 5 to 70 mol % of the A-sites, and manganese is contained in B-sites of the composite oxide.
