One aspect of the present disclosure is a method of manufacturing an aluminum alloy sheet for a can lid. The method includes a process of casting an ingot that includes an Si content of 0.20 mass % or more and 0.47 mass % or less, an Fe content of 0.30 mass % or more and 0.59 mass % or less, a Cu content of 0.11 mass % or more and 0.40 mass % or less, an Mn content of 0.70 mass % or more and 0.98 mass % or less, and an Mg content of 1.3 mass % or more and 3.7 mass % or less; a process of homogenizing treatment on the ingot; and a process of rolling the ingot. In the process of rolling, cold rolling is completed without performing heat treatment after performing hot rolling on the ingot.
