To provide a vehicular seat back which inhibits change of an attitude of an occupant during turning without deteriorating the ride quality.SOLUTION: A vehicular seat back 11 includes a pad 3 and a pressure receiving member 4. The pad has: a foam member 31 which elastically deforms; and a reinforcement member 32 which is applied to a rear surface of the foam member and reinforces the foam member. The pressure receiving member has: a base part 69 located at a center part as seen in a width direction of the seat back; and multiple side pieces 60 which respectively extend outward in the width direction from both sides of the base part. The pad has reinforcement reduction parts 321 which weaken reinforcement of the reinforcement member at positions which overlap with parts of the side pieces when viewed from a direction orthogonal to a surface of the seat back.SELECTED DRAWING: Figure 2
