Abstract:
The electronic component comprising:a case substrate having first and second principal surfaces facing each other; a plurality of substrate electrodes disposed on at least the first principal surface, each substrate electrode having a substantially spherical outer surface; an electronic component element, which is mounted on the first principal surface with a space therebetween and which is supported by the plurality of substrate electrodes in a point-contact manner; a conductive bonding material bonding the electronic component element to the plurality of substrate electrodes; and a cap having an opening extending in a downward direction, an opening edge thereof being fixed to the case substrate so as to cover the electronic component element; wherein the cap has an insulative surface, the opening edge of the cap is in contact with the outer surfaces of the plurality of substrate electrodes, and the following formula is satisfied: Lkâˆ’Wewhere Lk is the length of the case substrate in the longitudinal direction of the electronic component element, We is the length of the substrate electrode in the longitudinal direction of the electronic component element, and Lc is the length of the cap in the longitudinal direction of the electronic component element.
