MICRO-HOLE ARRAY AND METHOD FOR MANUFACTURING SAME

摘要

Provided are: a micro-hole array which is capable of holding optical fibers, etc. in precise alignment, and a method for manufacturing the micro-hole array such that micro-holes having high shape precision can be formed. The micro-hole array comprises 30 or more through holes 3 formed per 1 cm2 on a glass plate 2 with a thickness of 0.5 to 5 mm, the micro-hole array being characterized in that each through hole 3 has a cylindrical portion 5 that has a cylindricity of 5% or less of the hole diameter d1 of the through hole 3.
