摘要： A conductive composition for bonding includes a copper powder and a carboxylic acid mixed therewith. The carboxylic acid has a branched carbon chain in its structure. The copper powder comprises first copper particles and second copper particles. The first copper particles have a volume-based cumulative particle size D 50 of 0.11 µm or more and less than 1 µm at a cumulative volume of 50 vol% in a region of particle sizes of less than 1 µm in a particle size distribution of the copper powder that is determined using a scanning electron microscope. The second copper particles have a volume-based cumulative particle size D 50 of 1 µm or more and 10 µm or less at a cumulative volume of 50 vol% in a region of particle sizes of 1 µm or more in the particle size distribution of the copper powder that is determined using the scanning electron microscope. The carboxylic acid is contained in an amount of 6 parts by mass or more and 24 parts by mass or less per 100 parts by mass of the copper powder.

摘要： A copper paste for joining contains copper particles, a polycarboxylic acid having a melting point of 120°C or lower, and a dispersion medium. A method for manufacturing a joined body includes a first step of preparing a laminate in which a first member, a copper paste for joining, and a second member are laminated in this order, and a second step of heating the laminate under a gas atmosphere having a hydrogen concentration of 45% or less to sinter the copper paste for joining. Ajoined body includes a first member, a second member, and a sintered body of a copper paste for joining that joins the first member and the second member.
