The present invention aims to properly and stably bond an aluminum nitride sintered body to another aluminum nitride sintered body at relatively low temperatures without generating undesired gas. A first bonding material composition of the present invention is used to bond an aluminum nitride sintered body to another aluminum nitride sintered body including rare earth metal oxides, and includes (a) at least one from an alkaline earth metal fluorine compound as a fluorine compound and a rare earth metal fluorine compound or (b) at least one from an alkaline earth metal fluorine compound and a rare earth metal fluorine compound, and also includes a rare earth metal oxide.(A1, A2) Aluminum nitride sintered body(BB) Bonding layer(CC) Second layer(DD) First layerCOPYRIGHT KIPO 2015
