This method for producing an aluminum composite including porous sintered aluminum, includes: mixing aluminum powder with a sintering aid powder containing either one or both of titanium and titanium hydride to obtain a raw aluminum mixed powder; adding and mixing a water-soluble resin binder, water, a plasticizer containing at least one selected from polyhydric alcohols, ethers, and esters, and a water-insoluble hydrocarbon-based organic solvent containing five to eight carbon atoms into the raw aluminum mixed powder to obtain a viscous composition; shape-forming the viscous composition on an aluminum foil or an aluminum plate and causing the viscous composition to foam to obtain a formed object prior to sintering; and heating the formed object prior to sintering in a non-oxidizing atmosphere to obtain an aluminum composite which includes porous sintered aluminum integrally joined onto the aluminum foil or the aluminum plate, wherein when a temperature at which the raw aluminum mixed powder starts to melt is expressed as Tm (°C), then a temperature T (°C) of the heating fulfills Tm-10 (°C) ¤ T ¤ 685 (°C).
