1. A hot-dip plated steel material comprising:
a steel material; and
a hot-dip plated layer disposed on a surface of the steel material,
wherein the hot-dip plated layer has a chemical composition containing, in terms of mass %,
Al: 10.0 to 30.0%,
Mg: 3.0 to 15.0%,
Fe: 0.01 to 15.0%,
Si: 0 to 10.0%,
Ni: 0 to 1.0%, and
Ca: 0 to 4.0%, and
further containing one or two or more elements selected from the element group consisting of Sb: 0 to 0.5%, Pb: 0 to 0.5%, Cu: 0 to 1.0%, Sn: 0 to 2.0%, Ti: 0 to 1.0%, Cr: 0 to 1.0%, Nb: 0 to 1.0%, Zr: 0 to 1.0%, Mn: 0 to 1.0%, Mo: 0 to 1.0%, Ag: 0 to 1.0%, Li: 0 to 1.0%, La: 0 to 0.5%, Ce: 0 to 0.5%, B: 0 to 0.5%, Y: 0 to 0.5%, P: 0 to 0.5%, Sr: 0 to 0.5%, Co: 0 to 0.5%, Bi: 0 to 0.5%, In: 0 to 0.5%, V: 0 to 0.5%, and W: 0 to 0.5%, in an amount of 5% or less in total, and
the remainder: Zn and an impurity, and
the hot-dip plated layer has a diffraction intensity obtained from a result of X-ray diffraction measurement, the diffraction intensity satisfying a relationship of the following formulas (1a) and (2a):
0.5≤I(100)MgZn2/{I(002)MgZn2+I(101)MgZn2}≤2.5  (1a)
0.2≤I(111)α/I(200)α≤5.0  (2a)
wherein, in the formula (1a), I(100)MgZn2 represents an MgZn2 phase (100)diffraction intensity, I(002)MgZn2 represents an MgZn2 phase (002)diffraction intensity, and I(101)MgZn2 represents an MgZn2 phase (101)diffraction intensity, and in the formula (2a), I(111)α represents an α phase (111)diffraction intensity and I(200)α represents an α phase (200)diffraction intensity.
