发明名称 Wired circuit board and producing method thereof
摘要 A wired circuit board that can provide improved reliability on connection between the terminal portions and the external terminals while ensuring high productivity and cost reduction, and a production method thereof. After a conductive pattern 3 including terminal portions 6 to connect with external terminals 22 of an electronic component 21 and criterion marks 8 to determine presence or absence of an inhibitory portion 23 that may be formed due to formation of an insulating cover layer 4 to inhibit connection between the terminal portions 6 and the external terminals 22 are formed on the insulating base layer 2 simultaneously, the insulating cover layer 4 to cover the conductive pattern 3 and an opening 7 from which the terminal portions 6 and the criterion marks 8 are exposed is formed. Thereafter, the presence or absence of the inhibitory portion 23 is determined with reference to the criterion marks 8 exposed from the opening 7 of the insulating cover layer 4.
