described after ferritic stainless steel having components shown in table 1 was formed by melting and further formed into a slab hot rolling finishing temperature 800 u00b0 c coiling temperature 450 u00b0 c and sheet thickness 4 mm was performed by heating to 1 170 u00b0 c so that a hot rolled steel sheet was formed an average cooling rate from finish rolling to coiling that is from 800 u00b0 c to 450 u00b0 c was set to 20 u00b0 c sec the hot rolled steel sheet thus obtained was annealed at 900 u00b0 c to 1 200 u00b0 c for 30 to 300 seconds and further processed by pickling next after cold rolling was performed annealing was performed at 970 u00b0 c for 30 to 300 seconds and was further processed by pickling so that a ferritic stainless steel sheet sheet thickness 0 8 mm was formed a test piece width 30 mm and length 50 mm was cut out of the ferritic stainless steel sheet thus obtained and two surfaces of the test piece were polished with 600 abrasive paper and were then observed using a scanning electron microscope so called sem the grain diameter of a nb carbonitride was approximately several micrometers and the grain diameter of a nb carbide was approximately 1 u03bcm in addition it was confirmed that sulfur containing inclusions such as mns adhere to peripheries of the nb carbonitride and the nb carbide and are precipitated the grain diameters of all sulfur containing inclusions in one arbitrary viewing field having a size.
