1. A method for manufacturing a glass device having one or more through holes formed in a glass substrate, and a first wiring on a first surface of the glass substrate and a second wiring on a second surface opposite to the first surface being electrically connected to each other via the through holes, comprising the steps of:
providing the first wiring;
forming the through holes while thinning the glass substrate by etching;
providing wiring into the through holes and the second wiring; and
connecting the first wiring and the second wiring to each other via the wiring into the through holes, wherein
the glass substrate has the through holes formed with a thickness of 50 μm or more and 300 μm or less, and
the through holes have a shape of a truncated cone and having a second surface side opening being a bottom surface, and a ratio of (second surface side opening diameter/first surface side opening diameter) which is a relationship between a diameter of a first surface side opening and a diameter of the second surface side opening is 1.8 or more and 2.2 or less.
