Abstract:
An electronic component comprising:a base member having a plurality of electrode lands; an electronic component element having a substrate and a plurality of electrode pads provided on the substrate, the electronic component element being electrically and mechanically joined to the base member; a plurality of bumps located between the electronic component element and the base member, the plurality of electrode pads of the electronic component element and the corresponding electrode lands of the base member being respectively joined together via the bumps such that the electronic component is opposite to the base member and the plurality of bumps are in direct contact with the electrode pads of the electronic component element and the corresponding electrode lands of the base member; wherein the bumps located at the peripheral portion of the electronic component element have a height that is greater than the height of the bumps located in the approximate central portion of the electronic component element by about 1 &mgr;m to about 10 &mgr;m; and the base member is curved so that a forming portion of the electrode land located at the approximate central portion is close to the electronic component element.
