There are provided a molding apparatus and a battery tray manufactured thereby. The molding apparatus for molding a sheet that is fed along a first plane and manufacturing a battery tray includes an upper mold configured to press at least a part of the sheet from above the first plane to below the first plane and a lower mold configured to press at least a part of the sheet from below the first plane to above the first plane. It is possible to minimize a thickness of a product in a tray in which depths of battery accommodating grooves are large and to prevent incomplete molding from being generated.
