Abstract

PURPOSE:To obtain a wiring board which is low in cost and excellent in durability and electrical properties by a method wherein a protrudent groove is provided to a board provided with a printed wiring circuit on each of its sides or multilayered printed wiring circuits. CONSTITUTION:A conductor 5 is provided onto a printed wiring board 1, and at least a protrudent groove 6 is provided to an optical part of a board provided with the board 1. By providing the groove 6, a connector mounting area or space can be dispensed with and the board of this design can be made a monolithic conductor. By this setup, a printed wiring board excellent in electrical properties and low in cost can be realized.
