<p>Provided is a shaped aluminum object for manufacturing an integrally injection-molded aluminum/resin article, an integrally injection-molded aluminum/resin article using same, and a method for manufacturing the shaped aluminum object and the article, making it possible to effectively prevent dust from being generated on the surface of a shaped aluminum object and prevent a decrease in adhesive strength and airtightness near a resin gate on a resin joining surface between the shaped aluminum object and a resin molding. A shaped aluminum object, an integrally injection-molded aluminum/resin article using the object, and a method for manufacturing the shaped aluminum object, the shaped aluminum object having protrusions that extend in cornice shapes from depressions originating from asperities formed on a surface of the shaped aluminum object, wherein each observation cross-section (100-µm width) contains 150 to 800 observation lines passing from an empty space through aluminum and into another empty space on the basis of the protrusions when a plurality of observation lines that extend in the thickness direction of the shaped aluminum object from an empty space toward the asperities on the shaped aluminum object are drawn at a spacing of 0.1 µm from each other in a cross-section that extends in the thickness direction.</p> |
