Provided are an integrally injection-molded aluminum/resin article capable of having extremely high adhesion strength and air tightness at the interface between an aluminum shape made of an aluminum alloy and a molded resin integrally bonded to each other by injection molding, retaining excellent adhesion strength and air tightness in harsh environments in terms of temperature, humidity, dust, and the like, and exhibiting excellent durability and heat resistance, and a process for producing the same. The integrally injection-molded aluminum/resin article includes: an aluminum shape which is made of an aluminum alloy and has recesses derived from irregularities formed in the surface; and a molded resin which is integrally formed on the surface of the aluminum shape by the inject ion molding of a thermoplastic resin and has fitting portions formed in the recesses by the entering of the thermoplastic resin followed by solidification during the injection molding, the aluminum shape and the molded resin being locked with each other through the recesses and the fitting portions.
