Claim:
1. A connection body comprising: a circuit substrate; and an electronic component connected onto the circuit substrate via an anisotropic conductive adhesive agent; wherein the circuit substrate has substrate electrodes formed thereon and the electronic component has electrode terminals formed thereon, both of which having stepped sections formed on respective edge-side areas; wherein conductive particles contained by the anisotropic conductive adhesive agent are sandwiched between main surfaces of the substrate electrodes and the electrode terminals and between the stepped sections formed on the respective edge-side areas of the substrate electrodes and the electrode terminals; and wherein the conductive particles and each of the stepped sections of the substrate electrodes and the electrode terminals satisfy the following formula (1); wherein a is a height of the stepped section of the electrode terminals, b is a height of the stepped section of the substrate electrodes, c is a gap distance between each of the stepped sections and D is a diameter of the conductive particles.
