1. A molded sintered body, comprising:
a mayenite type compound,
an inorganic binder sintered material, and
a transition metal,
wherein
a content of the inorganic binder sintered material is 3 to 30 parts by mass with respect to 100 parts by mass of the molded sintered body,
in a pore size distribution of the molded sintered body obtained by pore size distribution measurement by a nitrogen adsorption method, the molded sintered body has at least one pore peak in each of a pore diameter range of 2.5 to 20 nm and a pore diameter range of 20 to 350 nm,
the mayenite type compound is a calcium aluminosilicate having the same type of crystal structure as mayenite, and
the inorganic binder sintered material is at least one porous material selected from the group consisting of porous alumina, porous silica, porous zirconia, porous magnesia, and porous titania.
