It does not perform an alloying treatment after plating, so that the activity of the surface can form, excellent in sliding characteristics Zn-based oxide layer without performing the alkaline pre-treatment with respect to the low hot-dip galvanized steel sheet. Further, increasing the area ratio of the produced Zn-base oxide layer on the surface, it makes it possible to manufacture the hot-dip galvanized steel sheet that can be increased any thickness. Subjected to hot-dip galvanizing to the steel sheet after subjected to temper rolling contact with an acidic solution having pH buffer action and, in conjunction O to form an oxide layer on a plated surface by washing with water after holding for 1-60 seconds after the end of the contact-coated steel sheet in the method, the temper rolling is a rolling roll with less rolling reduction of 5% or less by using a Ra of less than 2㎛, and then with that Ra is rolled to a reduction ratio of 3% or less by using a 0.1㎛ less bright roll, or Ra is rolled to a reduction ratio of 3% or less by using a 0.1㎛ less bright roll, and then rolled to a reduction ratio of 5% or less by using a roll Ra is less than the 2㎛.
