Abstract
A method for electrically connecting a surface electrode of a solar battery cell and a wiring member via a conductive adhesive film, wherein the conductive adhesive film contains an insulating adhesive and conductive particles, and wherein when the ten point height of roughness profile and maximum height of the surface of the surface electrode in contact with the conductive adhesive film are Rz (μm) and Ry (μm) respectively, the average particle diameter r (μm) of the conductive particles is equal to or greater than the ten point height of roughness profile Rz, and the thickness t (μm) of the conductive adhesive film is equal to or greater than the maximum height Ry.
