ELECTRONIC DEVICE AND METHOD OF MANUFACTURING THE SAME

摘要

PROBLEM TO BE SOLVED: To ensure electrical conduction between an electronic component mounted on a glass base material and an external electrode provided on the side opposite to the component mounted on the base, when a through electrode and the base are welded to each other at a temperature equal to or higher than a glass softening point.SOLUTION: An electronic device includes: a base 10; a through electrode 21 which passes through the base 10 and has a metal film 22 formed on both end surfaces after an insulating material on the surface is removed by polishing; an electronic component 40 which is provided on one surface of the through electrode 21 through a connection portion 30; an external electrode 70 which is provided on the side opposite to a side of the base 10 on which the electronic component 40 is provided; and a cap 50 which protects the electronic component 40 on the base 10.
