Hot-dip galvanized steel sheet

A hot-dip galvanized steel sheet, comprising:

• a basis steel sheet containing Si in an amount of 0.05 to 2.5% and Mn in an amount of 0.2 to 3%, by mass;
• a Fe plated layer formed on the basis steel sheet;
• and
• a hot-dip galvanized zinc layer formed on the surface layer of the basis steel sheet via the Fe plated layer,
• wherein upon observation of how the oxides containing Si and/or Mn occur in a region of dimensions of 1 μm or more by 1 μm or more in a perpendicular cross section including the vicinity of the interface between the basis steel sheet and the Fe plated layer under a transmission electron microscope at a magnification of 50000, even if a line segment with a length of 600 nm is drawn at any position in the field of vision of observation, the length of the portion in which the line segment and the oxides containing Si and/or Mn overlap with each other does not exceed 480 nm.
