    摘要： It is an object to provide a surface-treated steel sheet which contains no Cr, which is excellent in wet resin adhesion, and which can be used as an alternative to a conventional tin-free steel sheet and to provide a resin-coated steel sheet produced by coating the surface-treated steel sheet with resin. A surface-treated steel sheet including an adhesive layer which is disposed on at least one surface of the steel sheet and which contains Ti and at least one selected from the group consisting of Co, Fe, Ni, V, Cu, Mn, and Zn, the ratio of the total amount of Co, Fe, Ni, V, Cu, Mn, and Zn to the amount of Ti contained therein being 0.01 to ten on a mass basis, and a method for producing the surface-treated steel sheet. A surface-treated steel sheet including an adhesive layer which is disposed on at least one surface of the steel sheet, which has a thickness of 20 to 800 nm, which contains Ti, and which has bumps arranged with a line density of one or more per µm. The thickness of the adhesive layer is defined as the maximum height H from the lower surface of the adhesive layer to the bumps in a cross-sectional profile of the layer observed with a transmission electron microscope (TEM). The line density of the bumps is defined as the number of the bumps per unit length, the number thereof being determined on the assumption that one of the bumps is present when one or more intersections of an upper-level horizontal line and a profile curve are present between two intersections of a lower-level horizontal line and the profile curve, the upper- and lower-level horizontal lines being +10 nm apart from a center line located at a position given by the formula (H + L) / 2, where L represents the minimum height from the lower surface of the adhesive layer to the bottom of a recessed portion.

    摘要： The present invention proposes measures to decrease noise generated by an iron core of a transformer when grain oriented electrical steel sheets each having realized low iron loss through magnetic domain refinement are stacked to constitute the iron core. Specifically, the present invention proposes a method for manufacturing a grain oriented electrical steel sheet, comprising: subjecting a grain oriented electrical steel sheet comprising 2.0 mass% to 8.0 mass% Si and having a forsterite film on a steel sheet surface to flattening annealing at 800°C or higher wherein an in-furnace tension during flattening annealing is 10 MPa or less, and subjecting the grain oriented electrical steel sheet to magnetic domain refinement after final annealing such that thermal strain is introduced in a linear like manner in a direction intersecting a rolling direction of the steel sheet, with magnetic domain refinement interval D (mm) in the rolling direction, from a side of the steel sheet corresponding to the winding outer peripheral side of a coiled steel sheet at the stage of the final annealing, such that a deflection of the grain oriented electrical steel sheet is 3 mm or less per unit length: 500 mm in the rolling direction of the steel sheet,
