Zusammenfassung:	An aerosol can body having a surface pattern on a trunk portion in which a buckling strength is increased. A lower opening Ob to which a bottom lid 4 is attached is formed on one end of the seamless cylindrical trunk portion 2 formed of a steel sheet. A domed shoulder portion 3 having an arcuate cross-section is formed on the other end of the trunk portion 2 continuously from the trunk portion 2. An opening curled portion 5 that is diametrically smaller than the lower opening Ob is formed on a center of a leading end of the shoulder portion 3. the surface pattern 6 is formed on the trunk portion 2 between an upper end of the shoulder portion 3 side and a lower end of the lower opening Ob side by deforming the trunk portion 2 in a thickness direction. An upper region A that has a predetermined width including an upper end portion of the surface pattern 6 in an axial direction of the trunk portion 2 is formed above the trunk portion 2. Vickers hardness of at least the upper region a of the trunk portion 2 is greater than 200Hv but less than 250Hv.
