Abstract:
1. A method for producing a connection structure in which an electrode of a circuit board and an electrode of an electrical element are connected to each other by anisotropic conductive connection, the method comprising a heating and pressurizing step of connecting the electrode of the circuit board and the electrode of the electrical element by placing the electrical element on the circuit board via an anisotropic conductive adhesive, and heating and pressurizing the placed electrical element, wherein a product formed by dispersing solder particles having a melting temperature Ts in an insulating acrylic-based thermosetting resin is used as the anisotropic conductive adhesive, and a temperature at which the anisotropic conductive adhesive shows a minimum melt viscosity is Tv, the following formulas (1) and (2) are satisfied when:
