A stabilizer link provided in a vehicle provided with a suspension device and a stabilizer, and adapted to couple the suspension device and the stabilizer to each other, the stabilizer link comprising: a support bar made of metal; and ball joints each provided at both ends of the support bar, wherein the ball joints each include: a ball stud comprising a stud part at one end thereof having a stud shaft line and a ball part at the other end thereof, wherein said one end of the ball stud is fastened to a structural member; and a housing made of resin that rotatably supports the ball part of the ball stud; and the support bar includes: a body part extending in a nearly linear shape; and reinforcement parts each having a nearly annular shape and each provided at both ends of the body part, wherein the reinforcement parts each include a hole (12b1) having an inner semi-diameter size that allows passage of the ball part; characterized in that: the ball joints each further include a ball seat provided to be interposed between the ball part of the ball stud and a semispherical recessed part of the housing, the ball seat having a housing part for the ball part, and the ball seat including an encircling belt-shaped part for covering an equator part (21b1) of the ball part, the equator part (21b1) of the ball part being a part at which an encircling length in the horizontal direction of the ball part around the stud shaft line C as the central axis of rotation becomes the maximum; the reinforcement parts of the support bar each comprise: a base part (12b2) having a longitudinal section that extends in a direction of the stud shaft line; and a folded part (12b3) having a longitudinal section that extends in a direction orthogonal to the direction of the stud shaft line and inwardly toward the encircling belt-shaped part of the ball seat, and each reinforcement part composed of the base part and the folded part has a nearly L-shaped cross section continuously in a nearly annular manner; and the reinforcement parts are each embedded in the housing so as to surround the periphery of the encircling belt-shaped part of the ball seat. the stabilizer link comprising: a support bar made of metal;
