Galvanized steel sheet, member, and method for manufacturing the same

A galvanized steel sheet comprising:

• a base steel sheet;
• and a galvanized layer formed on the base steel sheet,
• wherein the base steel sheet has a steel microstructure including, in terms of area fraction,
• ferrite:
• less than 65%,
• a total of martensite and bainite:
• 25% or more, and
• retained austenite:
• 3% or more and 10% or less,
• 70% or more by area of the entire martensite in the steel microstructure at ⅛ to ⅜ of a thickness of the base steel sheet is tempered martensite containing carbide with an average grain size of 50 nm or more and 200 nm or less,
• the galvanized steel sheet has a tensile strength of 780 MPa or more and less than 1180 MPa,
• the galvanized steel sheet has a yield ratio of 0.60 or more, and
• an integrated amount of hydrogen released when the base steel sheet is heated from room temperature to 200° C. is 0.45 ppm by mass or less.
