PURPOSE:To obtain photoetching forming parts whose quality is uniform by constituting titled parts so that a reference hole for secondary working is secured as a hole having high accuracy without being damaged by a photoetching process, when manufacturing the parts for which the secondary working is required after the photoetching process. CONSTITUTION:A reference hole 5 for photoetching is made on a band-like base material 1, and simultaneously, a reference hole 4 for secondary working is brought to press punching, and driving immediately after it. Subsequently, photoetching for forming an external shape of parts is executed basing on the reference hole 5 for photoetching as a reference. Thereafter, a member in which the reference hole 4 for secondary working is punched is drawn out. Next, the secondary working is executed successively based on the reference hole 4 for secondary working drawn out in the previous process, as a reference, and photoetching forming parts are formed. Accordingly, the reference hole 4 for secondary working is not damaged by a photoetching process and a hole having high accuracy is secured, therefore, the secondary working such as bending, plastic forming, etc. can be executed with a stable quality. |
