Abstract:
1. A conductive adhesive comprising: conductive particles including a metal; a thermosetting resin; a flux activator; and a rheology control agent; wherein the conductive adhesive has a viscosity of 100 to 500 Pa·s, as measured using a rotation viscometer under conditions of a measurement temperature of 25° C. and a rotation rate of 0.5 rpm, and the conductive adhesive has properties whereby it is used for electrically connecting and adhering wiring members to an electrode connected to a solar battery cell, wherein a ratio of viscosity measured under conditions of a measurement temperature of 25° C. and a rotation rate of 0.5 rpm using a rotation viscometer after being left to stand at 25° C. for 24 hours, to viscosity as measured under conditions of a measurement temperature of 25° C. and a rotation rate of 0.5 rpm using a rotation viscometer before being left to stand is 0.7 to 1.5, and wherein the flux activator is a compound having a hydroxyl group and a carboxyl group.
