Claims

[Scope of utility model registration request]

The electronic component element on which the electrode is formed is housed in a case having an opening, and the electrode of the electronic component element is led out to the outside of the case through a lead-out electrode film formed at the edge of the opening of the case. What is claimed is: 1. A case structure for an electronic component, characterized in that a sloped portion is formed at an opening edge of the case, and the lead-out electrode film is formed on the sloped portion.
