Method for manufacturing dielectric wave guide

Abstract

A method for manufacturing a dielectric waveguide at a low manufacturing cost, the dielectric waveguide comprising a pair of conductor plates approximately parallel to each other and the dielectric strip provided therebetween, which can form a dielectric strip having accurate individual dimensions without generating cracks and chips during processing. The method comprises the steps of forming a resist pattern on a green sheet containing at least a powdered inorganic material and an organic binder, removing a predetermined amount of the green sheet corresponding to an opening in the resist pattern by the use of a mask, removing the resist pattern, and firing the green sheet. In the step of removing the predetermined amount of the green sheet, the rate of removal is continuously or intermittently changed along the depth direction of the green sheet.
