A suspension arm includes an arm portion and coupling portions, and the suspension arm is integrally made of a fiber reinforced plastics in entirety. The entire arm portion is made of a random fiber reinforced plastics. Each of the coupling portions is made of a continuous fiber reinforced plastics in which continuous fibers are oriented along a circumferential direction of an insertion hole over a region on a distal end side of the suspension arm, which continuously extends by at least a half circumference around a center axis of the insertion hole, the region including a position crossing a flat plane that is orthogonal to a straight line connecting center points of the insertion holes of elastic bushes and passes through the center point of the insertion hole.
