PROBLEM TO BE SOLVED: To produce a steel sheet for press forming small in defects and to provide a method for producing the same. SOLUTION: This steel sheet for press forming small in defects is the one obtd. by incorporating a steel contg. 0.0005 to 0.0070% C, 0.001 to 2.0% Si, 0.05 to 3.0% Mn, 0.001 to 0.150% P, 0.001 to 0.050% S, 0.0005 to 0.0080% N, <=0.005% acid soluble Al, 0.004 to 0.040% Ti, and the balance iron with inevitable impurities with inclusions with <=50μm particle size essentially consisting of Ti oxide, Mn oxide, Si oxide and alumina, and in which alumina is contained by <=30%.
