The invention discloses a spherical high-elongation aluminum alloy material for an inner container of an electric cooker and a manufacturing method of the spherical high-elongation aluminum alloy material. The aluminum alloy material comprises the following components in percentage by mass: 0.15-0.25% of Si, 0.5-0.7% of Fe, 0.05-0.2% of Cu, 1.25-1.45% of Mn, less than or equal to 0.03% of Mg, less than or equal to 0.05% of Zn, 0.03-0.05% of Ti and the balance of Al. The manufacturing method of the aluminum alloy material comprises the following steps of smelting, cast rolling, homogenizing annealing, rolling, trimming, finished product annealing, coil dividing, inspecting and packaging. According to the high-elongation aluminum alloy material for the spherical inner container of the electric cooker, a cast-rolled blank with lower cost is used, homogenizing annealing is carried out when the thickness of an aluminum coil blank is 10.0-12.0 mm, and then rolling, trimming and finished product annealing treatment
