Abstract
Powders of respective metal elements (Mn,Co) constituting a transition metal oxide (MnCoO) having a spinel type crystal structure are used as a starting material. A paste containing the mixture of the powders is interposed between an air electrode and an interconnector, and with this state, a sintering is performed, whereby a bonding agent according to the present invention can be obtained. This bonding agent has a 'co-continuous structure'. In the 'co-continuous structure', a thickness of an arm portion that links many base portions to one another is 0.3 to 2.5 μm. The bonding agent includes a spherical particle in which plural crystal faces are exposed to the surface, the particle having a side with a length of 1 μm or more, among the plural sides constituting the outline of the crystal face. The diameter of the particle is 5 to 80 μm.
