Zusammenfassung:PROBLEM TO BE SOLVED: To provide a conductive adhesive film eliminating insufficient adhesiveness even when used for the connection between an electrode and a wiring member of a solar cell substrate on which repeated hot/cold actions are applied for a long period of time at the outdoor, and having stable conductive performance.SOLUTION: A conductive adhesive film includes a phenoxy resin, an epoxy resin including at least a rubber-modified epoxy resin or an urethane-modified epoxy resin, a silane coupling agent, a latent curing agent for an epoxy resin, an acrylic resin, and a conductive filler, and has an elastic modulus at 40°C after curing of 1.2 GPa or more and 2.2 GPa or less.
