Abstract
Disclosed herein is a printed circuit board for an optical waveguide, including: a lower substrate; an insulation layer which has a through-hole and is formed on the lower substrate; an optical waveguide which is formed in the through-hole such that a clearance is present between the optical wave guide and an inner wall of the through-hole; and an adhesive material which is charged in the clearance. The printed circuit board for an optical waveguide is advantageous in that a lower clad material, a core material and an upper clad material are sequentially applied on the lower substrate partially, not entirely, based on the region in which a core is formed, and is then patterned to form an optical waveguide, so that the amounts of the lower and upper clad materials and the core material, which are used to form the optical waveguide, can be greatly decreased.
