Provided are: a conductive paste that, by means of using silver particles having predetermined crystalline change properties stipulated by means of XRD analysis, can easily control the sinterability of the silver particles in a conductive paste, and by extension after sintering processing, can stably obtain superior thermal conductivity and electrical conductivity; and a die bonding method using the conductive paste. The conductive paste or the like contains: silver particles having a volume average particle size of 0.1 to 30 μm as a sinterable conductive material; and a dispersing medium for resulting in a paste. When the 2&thetas;=38°±0.2° peak integrated intensity in the x-ray diffraction chart obtained by means of XRD analysis prior to sintering the silver particles is S1 and the 2&thetas;=38°±0.2° peak integrated intensity in the x-ray diffraction chart obtained by means of XRD analysis after sintering (at 250°C for 60 minutes) the silver particles is S2, the value of S2/S1 is a value in the range of 0.2-0.8. |
