| 摘要 |
An electronic component includes a plurality of first electrode pads arranged on a first substrate, a plurality of second electrode pads arranged at positions corresponding to the first electrode pads on a second substrate and a plurality of solder bumps which join together the first electrode pads and the second electrode pads. Here, the first substrate is located over the second substrate so that the first electrode pads and the second electrode pads are at positions which are shifted from opposite positions where the first electrode pads opposite to the second electrode pads, and at least a part of the solder bumps are solidified into hourglass-shaped.
