Abstract
The present invention is an electroconductive particle for forming an electrode including a precious metal particle including Pt or a Pt alloy and having an average particle diameter of 50 to 150 nm, a first ceramic particle including AlOor ZrOdispersed in the precious metal particle and having an average particle diameter of 5 to 50 nm, and a second ceramic particle including AlOor ZrObonded to an outer periphery of the precious metal particle and having an average particle diameter of 5 to 50 nm. The sum of the volume of the first ceramic particle and the volume of the second ceramic particle is preferably 2 to 40 vol % based on the whole electroconductive particle. A metal paste containing the electroconductive particle according to the invention is one from which an electrode film of low resistance and excellent durability can be manufactured and further excellent in adherence and conformability to a substrate.
