PROBLEM TO BE SOLVED: To provide silver oxide powders which show pyrolysis behaviors suitable for a use as a conductive component or a conductivity enhancer of a conductor paste of calcination type, which is superior in pyrolysis characteristics and calcination characteristics even in the case the conductor paste is calcined at a relatively low temperature and for a short time, and furthermore which has an appropriate activity, is superior in stability, is easy to handle and can be preserved for a long time, the manufacturing method and the conductor paste capable of forming a silver coating superior in conductivity and adhesiveness using these silver oxide powders. SOLUTION: As for the silver oxide powders in which the average primary particle diameter by electron-microscopic observation is 0.1 to 0.3μm, and in which the average aggregated particle diameter (D<SB>50</SB>) calculated by a laser diffraction scattering type particle size distribution measurement is 1.0 to 2.5μm, and which are composed of the silver oxide particles of which the particle surface is coated by polyether, when a heat treatment is carried out in air atmosphere, the main pyrolysis reaction of silver oxide occurs within a temperature range of 400 to 460°C.
