The present invention provides a method for producing a thin cold rolled steel sheet, which is adapted to be formed into, for example, an external automotive plate. The method includes an appearance-finishing step by bake-coating as a final step after drawing (such as press molding), and has a remarkably high baking hardenability. The baking hardenability is a property for improving the yield strength due to the heating during the bake coating treatment and is particularly advantageous for producing a light weight automobile and for compensating the deterioration of dent resistance of the automotive plate due to the lowering of its weight, (without deteriorating the r value). The latter is an indication of the press moldability of the thin steel sheet. Furthermore, the present invention discloses an effective compounding amount of Ti which acts to fix C, S and N contained in the steel, and a continuous annealing condition properly selected depending upon the effective amount of Ti.
