Zusammenfassung:	To provide an aluminum alloy forged product with superior mechanical properties at room temperature, and a method for producing the same.SOLUTION: An aluminum alloy forged product has an alloy composition where the ratio (Fe/Mn) of Fe content to Mn content is from 0.3 to 1.2 in mass ratio, with the balance being Al and unavoidable impurities. When the fatigue strength of the longitudinal center of the long part is defined as P1 and the fatigue strength of the longitudinal boundary between the long part and the connection part is defined as P2, the value of P1/P2 ranges from 1.00 to 1.07.SELECTED DRAWING: Figure 1 【課題】常温における機械的特性に優れたアルミニウム合金製鍛造品及びその製造方法を提供する。【解決手段】アルミニウム合金製鍛造品は、Ｍｎの含有量に対するＦｅの含有量の比Ｆｅ／Ｍｎが質量比で０．３以上１．２以下であり、残部がＡｌ及び不可避不純物からなる合金組成を有し、前記長尺部の長手方向の中央部の疲労強度をＰ１、前記長尺部と前記連結部の長手方向の境界部の疲労強度をＰ２としたとき、Ｐ１／Ｐ２の値が１．００以上、１．０７以下の範囲である。【選択図】図１
