PROBLEM TO BE SOLVED : To provide a manufacturing management method of a vehicular wire harness capable of imparting a large amount of information, high in confidentiality, and rich in flexibility. SOLUTION : A mark is attached to a surface of a manufactured connector housing 10 by attaching information imparting ink containing one or more kinds of information presentation substances (oxide powder of a rare-earth element is preferable) depending on manufacturing management information. In reading the information, fluorescence emitted from the information presentation substance(s) is detected by irradiating the surface of the connector housing 10 with an ultraviolet ray or the like. The form of presence of the information presentation substance(s) is detected by the wavelength/amount and the like of the fluorescence, and the manufacturing management information related to the form of presence can be identified.
