Abstract
An engine hood structure including a hood panel, and a porous metal layer disposed on an inside of the hood panel. The porous metal layer has a density increased in a direction extending from an outer periphery of the engine hood structure toward a central portion of the engine hood structure. The porous metal layer is constructed such that a plateau stress generated in the porous metal layer upon a compression test is increased in a direction extending from an outer periphery of the engine hood structure toward a central portion of the engine hood structure.
