A vehicle stabilizer made of a rod-shaped steel material comprising: a torsion section extending in a width direction of a vehicle; a pair of bend sections (21, 22) continuous with both ends of the torsion section; and a pair of arms continuous with the respective bend sections, characterized in that: the bend sections each comprise a bend interior section which is located at 0° and which has compressive residual stress formed by shot peening from a surface of the steel material to a first depth, a bend exterior section which is located at 180° and which has compressive residual stress formed by shot peening from the surface to a second depth, a first side section which is located at 90° and which has compressive residual stress formed by shot peening from the surface to a third depth, and a second side section which is located at 270° and which has compressive residual stress formed by shot peening from the surface to a fourth depth, when a center of an inside of a bend is defined as 0°, a center of an outside of the bend is defined as 180°, a midpoint between 0° and 180° is defined as 90°, and an opposite side to 90° is defined as 270° with respect to positions in a circumferential direction of a radial cross section; a sum of the compressive residual stress from the surface to the first depth of the bend interior section is greater than a sum of the compressive residual stress from the surface to the second depth of the bend exterior section; and a sum of the compressive residual stress from the surface to the fourth depth of the second side section is greater than a sum of the compressive residual stress from the surface to the third depth of the first side section. a torsion section extending in a width direction of a vehicle; a pair of bend sections (21, 22) continuous with both ends of the torsion section; and a pair of arms continuous with the respective bend sections, characterized in that: the bend sections each comprise a bend interior section which is located at 0° and which has compressive residual stress formed by shot peening from a surface of the steel material to a first depth, a bend exterior section which is located at 180° and which has compressive residual stress formed by shot peening from the surface to a second depth, a first side section which is located at 90° and which has compressive residual stress formed by shot peening from the surface to a third depth, and a second side section which is located at 270° and which has compressive residual stress formed by shot peening from the surface to a fourth depth, when a center of an inside of a bend is defined as 0°, a center of an outside of the bend is defined as 180°, a midpoint between 0° and 180° is defined as 90°, and an opposite side to 90° is defined as 270° with respect to positions in a circumferential direction of a radial cross section; a sum of the compressive residual stress from the surface to the first depth of the bend interior section is greater than a sum of the compressive residual stress from the surface to the second depth of the bend exterior section; and a sum of the compressive residual stress from the surface to the fourth depth of the second side section is greater than a sum of the compressive residual stress from the surface to the third depth of the first side section. the bend sections each comprise a bend interior section which is located at 0° and which has compressive residual stress formed by shot peening from a surface of the steel material to a first depth, a bend exterior section which is located at 180° and which has compressive residual stress formed by shot peening from the surface to a second depth, a first side section which is located at 90° and which has compressive residual stress formed by shot peening from the surface to a third depth, and a second side section which is located at 270° and which has compressive residual stress formed by shot peening from the surface to a fourth depth, when a center of an inside of a bend is defined as 0°, a center of an outside of the bend is defined as 180°, a midpoint between 0° and 180° is defined as 90°, and an opposite side to 90° is defined as 270° with respect to positions in a circumferential direction of a radial cross section; a sum of the compressive residual stress from the surface to the first depth of the bend interior section is greater than a sum of the compressive residual stress from the surface to the second depth of the bend exterior section; and a sum of the compressive residual stress from the surface to the fourth depth of the second side section is greater than a sum of the compressive residual stress from the surface to the third depth of the first side section.
