摘要：
The present invention provides a bonding material and a method of bonding for metal bonding at a bonding interface capable of a higher bonding strength at a lower temperature without application of pressure, compared to a bonding material of metal particles having an average particle size of not greater than 100 nm. An electrically conductive bonding material including (A) silver particles, (B) silver oxide, and (C) a dispersant including organic material containing not more than 30 carbon atoms as essential components, wherein a total amount of (A) the silver powder, (B) the silver oxide powder, and (C) the dispersant including an organic material containing not more than 30 carbon atoms is in a range of 99.0% to 100% by weight, is provided. In other words, no resin binder is contained.
