SOLUTION: The surface-treated steel sheet includes a titanium-containing adhesive coating film having a thickness of 20-800 nm formed on at least one side of the steel sheet. The adhesive coating film has protrusions at a linear density of 1 piece/μm or more. The thickness of the adhesive coating film means the maximum height H of protrusions as measured from the lower side of the coating film in an examination of the profile of a cross-section of the coating film with a TEM. The linear density of the protrusions means the following. The minimum height of the bottoms of recesses as measured from the lower side of the coating film is expressed by L, and two horizontal lines are drawn at the upper and lower levels of ±10 nm based on the position (H+L)/2 as a center. When the range between two points where the lower-level horizontal line intersects the cross-section profile curve includes one or more points where the upper-level horizontal line intersects the profile curve, then the number of the protrusions present in this range is taken as 1. The number of the protrusions per unit length is thus determined as the linear density of the protrusions. COPYRIGHT: (C)2010,JPO&INPIT
