Abstract
An oxygen source-containing composite nanometal paste including at least composite nanometal particles, in which an organic coating layer is formed around a submicron or smaller silver core, and an oxygen source, which feeds oxygen contributing to pyrolysis at a pyrolysis temperature range in which the organic coating layer is pyrolyzed. The oxygen source comprises an oxygen-containing metal compound, and the oxygen content of the oxygen source is within a range of 0.01 mass % to 2 mass % per 100 mass % of the composite nanometal particles.
