Abstract

PURPOSE:To lower the cost and increase flexibility by injecting liquid in a highly flexible and transparent tubular medium thereby constituting a light guide. CONSTITUTION:For example, water is used as a core material (medium 1), and, for example, polyvinyl chloride is used as a clad material (medium 2). By the constitution using such materials, the light guide which is inexpensive and highly flexible is obtained.
