Abstract
A heat-fused unitary ferrule includes a first glass substrate and a second glass substrate. The first glass substrate and the second glass substrate are unitarily joined by heat-fusion. A method for producing a heat-fused unitary ferrule includes the steps of: bringing a surface to be heat-fused of the first glass substrate having a groove for fixing an optical fiber into contact with a surface to be heat-fused of the second glass substrate; and subjecting the first and second glass substrates to heat-fusion at a temperature ranging from (Tg1-100).degree. C. to (Tg2+150).degree. C. (Tg1 denotes the higher glass transition temperature, and Tg2 denotes the lower glass transition temperature of the first and second glass substrates).
