Provided are an alloyed hot dip galvanized steel sheet and a hot dip galvanized steel sheet having superior plating properties, workability in terms of bending workability and hole-expandability, and delayed fracture resistance, and furthermore superior shock absorption resistance of at least 980 MPa. The high-strength plated steel sheet has a plating layer on the surface of a base material steel sheet, contains predetermined steel components, and has, in sequence from the interface between the base material steel sheet and the plating layer towards the base material steel sheet side, a soft layer having a Vickers hardness of no greater than 90% of the Vickers hardness at the t/4 section of the base material steel sheet, where t is the thickness of the base material steel sheet, and a hard layer configured from a structure having primarily martensite and bainite. The average depth (D) of the soft layer is at least 20 [mu]m, and the average depth (d) of an inner oxide layer is at least 4 [mu]m and less than D.
