Abstract:
1. A circuit component comprising: an IC chip; and a substrate; wherein the IC chip and the substrate are connected to each other via an electrically conductive adhesive containing electrically conductive particles, wherein the IC chip has a mounting surface on which a bump electrode and a non-electrode surface are provided, the non-electrode surface being a portion of the mounting surface other than a portion in which the bump electrode is formed, wherein electrically conductive particles in a first state exist between a surface of the substrate and the non-electrode surface, the first state being a state in which the electrically conductive particles are in contact with both the surface of the substrate and the non-electrode surface, and wherein electrically conductive particles in a second state exist between the surface of the substrate and the bump electrode, the second state being a state in which the electrically conductive particles are placed so as to be more flattened than the first state and dig into the bump electrode.
