PROBLEM TO BE SOLVED: To make high-speed production possible by utilizing a magnesium alloy which permits weight reduction and shortening a post working process step to the maximum possible extent in manufacturing of parts for shielding electromagnetic waves. SOLUTION: The method of manufacturing the parts for shielding the electromagnetic waves by using the magnesium alloy includes a material heating process step of cutting the material of the magnesium alloy and homogeneizing the material by relieving stresses so as to be advantageous in molding the products, a process step of hot molding and working for fabricating the products by using the heated material, a trimming process step of neatly trimming the products by cutting off the unnecessary edges, fins, etc., of the fabricated products after undergoing the process step of the hot molding and working, a film treating process step of performing rust preventive work on the finished products after undergoing the trimming process step and a painting work of painting the products after undergoing the film treating process step.
