Zusammenfassung:	There is provided a bonding paste capable of forming a uniform bonding layer by reducing occurrence of voids at edges even when a bonding area is large, and bonding method using the paste, and provides a metal paste for bonding containing at least metal nanoparticles (A) having a number average primary particle size of 10 to 100 nm, wherein a cumulative weight loss value (L100) when a temperature is raised from 40° C. to 100° C. is 75 or less, and a cumulative weight loss value (L150) when a temperature is raised from 40° C. to 150° C. is 90 or more, and a cumulative weight loss value (L200) when a temperature is raised from 40° C. to 200° C. is 98 or more, based on 100 cumulative weight loss value (L700) when the paste is heated from 40° C. to 700° C. at a heating rate of 3° C./min in a nitrogen atmosphere.
