Abstract
A method of inspecting a degree of air bubbles which are mixed into an ultraviolet curable resin for an optical fiber having viscosity of 1.2 Pa·s to 6.2 Pa·s at a temperature of 25±5° C., is performed in such a manner that the ultraviolet curable resin for an optical fiber which is an inspecting target is put into a sealed apparatus, then the inside of the sealed apparatus is decompressed to be a predetermined pressure, and then the sealed apparatus is left to stand as it is for a predetermined time. If a ratio of the volume expansion of the ultraviolet curable resin for an optical fiber is equal to or less than a predetermined threshold, the ultraviolet curable resin for an optical fiber is recognized as an accepted product.
