Abstract

Provided is a high-strength hot-dip-plated steel sheet that has a tensile strength of 780 MPa or more and that has favorable workability. Also provided is a production method for the high-strength hot-dip-plated steel sheet. A high-strength hot-dip-plated steel sheet that has a steel sheet and a plating layer that is formed upon the steel sheet. The high-strength hot-dip-plated steel sheet is characterized in that the steel sheet comprises a specific component composition and in that the steel structure of the steel sheet contains, by area ratio, 20% or less (including 0%) of a ferrite phase, 35%-90% of a bainite phase, and 10%-65% of a martensite phase and contains, by number density per mm2, 400 or fewer inclusions that have an equivalent circle diameter of more than 5.0 µm, the granular martensite that constitutes the martensite phase having an average grain size of 3.0 µm or less, and the maximum distance between adjacent martensite being 5.0 µm or less.
