PROBLEM TO BE SOLVED: To solve the following problems with the embossed single peak plastic spectacle frame, that there is a large loss by chipping, twisting, etc., during polishing, a cost reduction is not possible unless large-lot production, further, the period for delivery in production is needed and a production cost is greater, also, the entire part of the frame consists of the same material and therefore there is a limitation in the improvement of designs. SOLUTION: This spectacle frame is provided with the strength to withstand rough polishing and finish polishing by fabrication consisting of machining with a cutting machine and ending the machining in the state of connecting right and left lens shapes (lens supporting frames). Further, the novel improvement in designs not possible heretofore or the reduction of production loss and the curtailment of the cost and made possible by mounting of a single peak bridge section by post attachment after welding with the patterns, colors and directions of the patterns different from those of a main body.
