Abstract: A bonding material and a related manufacturing method are disclosed in which an unfired ceramic body A, internally formed with a cavity portion or a surface formed with a concaved portion, and an unfired ceramic body B are bonded to each other. The bonding material is applied to a bonding area between the unfired ceramic bodies A and B in a thickness ranging from 10 to 25 ?m to provide a bonded body that is fired to obtain a ceramic bonded body. The bonding material contains an inorganic powder, an organic binder and an organic solvent in a composition to satisfy relationships 0?X—Z?2.6 and 0?Y—Z?2.6 where “X” represents a firing contraction ratio (%) of the unfired ceramic body A, “Y” a firing contraction ratio (%) of the unfired ceramic body B, and “Z” a firing contraction ratio of tie bonding material.
