A martensitic stainless steel sheet comprises a chemical composition containing, in mass %, C: 0.035% to 0.090%, Si: 0.01% to 1.0%, Mn: 0.01% to 0.90%, P: 0.050% or less, S: 0.050% or less, Cr: 10.0% to 14.0%, Ni: 0.01% to 0.40%, Al: 0.001% to 0.50%, V: 0.05% to 0.50%, and N: 0.050% to 0.20%, with the balance being Fe and inevitable impurities, wherein a content of C and a content of N in the chemical composition satisfy C %+N % 0.10% and N % C %, the number of precipitates with a major axis length of 200 nm or more in a surface layer of the martensitic stainless steel sheet is 25 or less per 100 μm2, and the martensitic stainless steel sheet has a tensile strength of 1300 MPa or more, a proof stress of 1100 MPa or more, and an elongation of 8.0% or more.
