The invention relates to a method for manufacturing an aluminum coated steel sheet, in which heat resistance is improved, comprising: a step for preparing a steel sheet; and a step for forming a plating layer on a surface of the steel sheet by using an aluminum target through a sputtering process. Moreover, an aluminum coated steel sheet according to the invention comprises: a steel sheet; and an aluminum based plating layer, which is plated on a surface of the steel sheet. The plating layer is plated through a sputtering method, and an inter-metal compound layer is not formed between the steel sheet and the plating layer. The present invention provides an aluminum coated steel sheet, in which a discoloration of a surface is generated at high temperatures, which is over 400, because diffusion of Fe through an inter-metal compound layer is prevented by plating an aluminum or an aluminum alloy to a sputtering method.
