A can at least a part of which is made of an electrolytically chromated steel sheet, said steel sheet having such a surface that when it is degreased in acetone for 1 minute and analyzed by an Auger electron spectrometer at an incident electron accelerating voltage of 3 KeV, a modulation voltage of 3 V, a modulation frequency of 12 to 20 KHz and a degree of vacuum of at least 6x10-8 torr, the ratio of the peak-peak distance (OP-P) of KL2.3L2.3 of oxygen to the base-peak distance (CrB-P) of L3M2.3M4.5 of chromium in the resulting Auger electron spectrum satisfies the following relation: 6.5>/=(OP-P)/(CrB-P)>/=1.5. |
