A NOx sensor 100 is produced by forming a stack with a ceramics paste including ceramic particles, a resin, a solvent, and one or more additives selected from additives of a first group having a first structure containing one or more selected from ether structures, urethane structures, hydroxy group-containing structures, ester structures, and acrylic structures and additives of a second group having any one or more structures of the additives of the first group and a second structure containing one or more selected from imidazoline structures, ethylenediamine structures, and amine structures. The ceramics paste contains any one of the additives of the first group and the second group and thus has an appropriate affinity for a cutting edge at the time of cutting a laminated body before the firing of the NOx sensor 100.
