<P>PROBLEM TO BE SOLVED: To provide an electronic component which allows a reliable electric connection via a projection electrode with an underfill material applied. <P>SOLUTION: This electronic component comprises a projection electrode 5 composed of conductive materials and a dummy projection 6 taller than the projection electrode 5 on a substrate 2. A number of dummy projections 6 are created outside of an area having the projection electrode 5, each having a height nearly equal to that of the projection electrode. The melting point of each projection 6 lies in a temperature range except the melting point of the projection electrode 5. In addition, when the projection electrode 5 is connected to the outside, electronic component position information can be detected via the projection 6. <P>COPYRIGHT: (C)2008,JPO&INPIT |
