Abstract:
A manufacturing method of a glass substrate having through holes includes (i) irradiating at a through hole forming target position on a first surface of the glass substrate with a laser light; and (ii) performing a wet etching treatment on the glass substrate.   During the wet etching treatment being performed on the glass substrate, an ultrasonic vibration with a frequency of less than 40 kHz is applied to an etchant over at least a part of the wet etching period, referred to as an ultrasonic vibration application period.

Claim (Index 10):
A glass substrate comprising:\n a first surface; a second surface; and a through hole that penetrates from the first surface to the second surface, wherein the through hole has a first aperture with a first diameter \u03d5 1  on the first surface and a second aperture with a second diameter \u03d5 2  on the second surface, the first diameter \u03d5 1  being larger than or equal to the second diameter \u03d5 2 , wherein the through hole has a constriction part inside the glass substrate, the constriction part having a third diameter \u03d5 3  in a cross-section orthogonal to an extending direction of the through hole, and the third diameter \u03d5 3  being less than the second diameter \u03d5 2 , wherein an aspect ratio of a thickness of the glass substrate (t) to the first diameter (\u03d5 1 ), t/\u03d5 1 , is 25 or less, and a ratio of the third diameter (\u03d5 3 ) to the first diameter (\u03d5 1 ), \u03d5 3 /\u03d5 1 , is 0.50 or more, and wherein both an arithmetic average roughness Ra of the first surface near the first aperture and an arithmetic average surface roughness Ra of the second surface near the second aperture are 0.05 \u03bcm or less.
