Abstract
An ultrafine tube is produced by a method comprising the steps of applying a highly polymerized material on a substrate to form a resist layer on a surface of said substrate, applying a laser beam to the resist layer under such a condition that said resist layer is melted to form an ultrafine tube between the substrate and resist layer in the predetermined pattern.
