Method for connecting electronic part and joined structure

A method for connecting an electronic part, comprising:

• mixing a dispersing solvent, an adhesive resin which is dissolved in the dispersing solvent, conductive particles, and insulating particles which have smaller particle diameters than those of the conductive particles so as to prepare an anisotropic conductive adhesive;
• placing a terminal of a substrate and a terminal of an electronic part so as to face each other via the anisotropic conductive adhesive, and applying heat and pressure to the substrate and the electronic part so as to sandwich the conductive particles between the terminal of the substrate and the terminal of the electronic part to thereby deform the conductive particles,
• wherein the pressure is smaller than pressure at which the conductive particles are destroyed, and smaller than pressure at which the particle diameters of the conductive particles become equal to the particle diameters of the insulating particles and,
• wherein the insulating particle is an organic-inorganic hybrid particle which is an organic particle whose surface has an inorganic material bonded thereto.
