PROBLEM TO BE SOLVED: To maintain sufficient strength with which a land 2 and a conductive ball 3 are fixed, and to ensure the fixation of the conductive ball 3 with the land 2 in an electric component that comprises: a circuit element on one surface of an insulation substrate 1 that constitutes an electric component; the land 2 for connecting a terminal that constitutes the circuit element; and the conductive ball 3 that is connected to the land 2. SOLUTION: The land 2 for connecting terminals and the terminals comprising the conductive ball 3 are fixed by a conductive resin 4, wherein the conductive ball 3 is formed of Cu of which the surface is coated with solder. The solder preferably comprises Su alone. COPYRIGHT: (C)2005,JPO&NCIPI
