According to the present invention, in a plan view of a seat surface (10a), a plane area of a part surrounded by an inner edge (17a) of a rear part (17) in a left-right direction (X) and a contour (L) is larger than a plane area of a part sandwiched by an inner edge (18a) of a front part (18) in the left-right direction (X) and the contour (L) in the left-right direction (X). In addition, a part of a pair of left and right second synthetic resin materials forming a lower part having a maximum gap therebetween in the left-right direction (X) is positioned in a thigh rest part (14) and a part having a minimum gap is positioned in a hip rest part (15), and a maximum value (W1) of the gap between the pair of left and right second synthetic resin materials forming the lower part in the left-right direction (X) is two times or more a minimum value (W2) of the gap in the left-right direction (X).
