Claim 0:
1. A packaging glass comprising:
a core layer and an upper layer,
wherein the core layer comprises a supporting substrate comprising a glass substrate with a first surface and a second surface facing each other, and comprising a core via penetrating through the first surface and the second surface; and
a core distribution layer comprising an electrically conductive layer respectively disposed on at least a part of the first surface and the second surface, and an electrically conductive layer which electrically connects them to each other through the core via;
wherein the upper layer comprises an electrically conductive layer disposed on the first surface and electrically connecting the core distribution layer and an element unit, and;
wherein an average inner diameter of a part with the minimum inner diameter within a core via formed on the glass substrate is 50 μm to 95 μm and satisfies the condition of Equation 1 below.

0.83×D90≤D50≤1.25×D10  [Equation 1]

In the Equation 1, D50 is a value corresponding to 50% in the diameter distribution of the minimum inner diameter, D90 is a value corresponding to 90% in the diameter distribution of the minimum inner diameter, and D10 is a value corresponding to 10% in the diameter distribution of the minimum inner diameter.
