摘要：
In a cutting edge 2 of a razor blade, a non-nitrided layer 9 containing Ti, Al, and Cr is formed on opposite surfaces 7, 8 of a base plate 3 as a portion of a coating layer 4. A remaining layer 15 containing Ti, Al, Cr, and N is formed on opposite surfaces 10, 11 of the non-nitrided layer 9 as a portion of a nitrided layer 12 of the coating layer 4. A surface layer 18 containing Ti, Al, Cr, and N is formed on opposite surfaces 16, 17 of the remaining layer 15 as a portion of the nitrided layer 12 of the coating layer 4. A fluororesin layer 6 is formed on opposite surfaces 19, 20 of the surface layer 18 with a bonding layer 5 containing Cr and Al in between. The coating layer 4 including the non-nitrided layer 9 and the nitrided layer 12 further improves the cutting edge 2, enhances cutting performance of the cutting edge 2, and maintains the enhanced cutting performance to improve the durability of the cutting edge 2.
