To provide a production method of a fiber reinforced resin molded article and a mold that allows a resin to easily flow into between a fiber base material and an insert member.SOLUTION: A fiber reinforced resin molded article is produced by using a mold 1 comprising: a first mold 10 provided with a recess 11a into which an insert member 40 can be inserted, and a holding mechanism 20 capable of holding the insert member 40 in the recess 11a; a second mold 30 on which a fiber base material 50 can be disposed so as to face the insert member 40; the insert member 40; and the fiber base material 50. The mold 1 can be clamped while being provided with a gap L between the fiber base material 50 and the insert member 40. The gap L becomes a passage of a resin R to allow the resin R to easily flow into between the insert member 40 and the fiber base material 50.SELECTED DRAWING: Figure 2 【課題】繊維基材とインサート部材との間に樹脂が流れ込みやすい繊維強化樹脂成形体の製造方法及び成形用金型とすること。【解決手段】インサート部材４０を挿入可能な凹部１１ａ、及び凹部１１ａにインサート部材４０を保持可能な保持機構２０を備える第１金型１０と、インサート部材４０に対向するように繊維基材５０を配置可能な第２金型３０と、インサート部材４０と、繊維基材５０と、を備えた成形用金型１を用いて、繊維強化樹脂成形体を製造する。成形用金型１は、繊維基材５０とインサート部材４０とに隙間Ｌを設けて型締めをすることが可能なものである。この隙間Ｌが樹脂Ｒの流路となり、インサート部材４０と繊維基材５０との間に樹脂Ｒが流れ込みやすくなる。【選択図】図２
