Abstract:
An electronic component comprising:a mounting substrate having a surface on which an electrode is formed; a circuit element which comprises a substrate having a surface on which a circuit is formed; a bump electrode electrically connecting the circuit on the circuit element and the electrode on the mounting substrate together; an element-side seal ring provided on the surface of the substrate of the circuit element along an entire periphery of the substrate; a substrate-side seal ring provided on the surface of the mounting substrate along an entire periphery of the mounting substrate; and a sealing material provided between the element-side seal ring and the substrate-side seal ring to join the circuit element and the substrate together such that the surface of the circuit element and the surface of the substrate are opposed to each other and that a hermetic space between the circuit element and the substrate is defined, wherein the sealing material is a low-temperature soldering material, the sealing material is different from the bump electrode material, and the sealing material has a melting temperature below that of the bump electrode material.
