PROBLEM TO BE SOLVED: To reduce the usage of wax materials, and to form a wax material layer in a desired shape at a cover body. SOLUTION: A band-shaped cover member 30 is prepared, and a guide hole 30a is perforated by continuous press working. Then, the cover member 30 is operated with Ni plating 31, and then operated with Au plating 32 as a base for forming a wax material layer 34. Then, the wax materials are screen-printed on the Au plating 32 ((h) wax material paste print process), and then made to reflow so that the Au plating 32 can be coated with the wax materials ((i) wax material reflow process), and the wax material layer 34 is formed. Then, the outer shape of a cover body 3 is punched by press working, and finally anneal/packaging is executed. COPYRIGHT: (C)2004,JPO&NCIPI
