The stainless steel foil according to claim 1 , wherein the foil thickness is 20 to 100 μm. 6. A catalyst carrier for an exhaust gas purifying device using the stainless steel foil according to claim 1 . 7. The stainless steel foil according to claim 2 , wherein the stainless steel foil comprises, in percent by mass, 3.0% to 5.5% of Mo. 8. The stainless steel foil according to claim 2 , further comprising at least one of 0.01% to 0.20% of Hf (in percent by mass), 10 to 300 ppm of Ca, 15 to 300 ppm of Mg, and 3 to 100 ppm of B (in ppm by mass). 9. The stainless steel foil according to claim 3 , further comprising at least one of 0.01% to 0.20% of Hf (in percent by mass), 10 to 300 ppm of Ca, 15 to 300 ppm of Mg, and 3 to 100 ppm of B (in ppm by mass). 10. The stainless steel foil according to claim 7 , further comprising at least one of 0.01% to 0.20% of Hf (in percent by mass), 10 to 300 ppm of Ca, 15 to 300 ppm of Mg, and 3 to 100 ppm of B (in ppm by mass). 11. The stainless steel foil according to claim 2 , wherein the foil thickness is 20 to 100 μm. 12. The stainless steel foil according to claim 3 , wherein the foil thickness is 20 to 100 μm. 13. The stainless steel foil according to claim 7 , wherein the foil thickness is 20 to 100 μm. 14. The stainless steel foil according to claim 4 , wherein the foil thickness is 20 to 100 μm. 15. The stainless steel foil according to claim 8 , wherein the foil thickness is 20 to 100 μm. 16. The stainless steel foil according to claim 9 , wherein the foil thickness is 20 to 100 μm. 17. The stainless steel foil according to claim 10 , wherein the foil thickness is 20 to 100 μm.
