Abstract

An automotive member or a feed oil pipe includes: a member made of a ferritic stainless steel containing predetermined components containing 10.5% to 18.0% of Cr in mass %; a metal fitting made of an aluminized stainless steel sheet, the metal fitting being attached to the member; and a gap structure defined between the member and the metal fitting, the gap structure being exposed to a chloride environment, where the metal fitting has an Al-plating weight per unit area of 20 g/mor more and 150 g/mor less on a surface corresponding to a gap of the gap structure, and surfaces of the metal fitting and the non-aluminized member other than the gap are coated with a cation electrodeposition coating film having a thickness of 5 μm to 35 μm.
