Provided is a vehicle seat which, when subjected to a complex input load during a rear collision, can stably deform at a specific portion thereof to efficiently absorb impact energy in the rear collision. A vehicle seat (S) is provided with: frame's side sections (15a, 17a) located at the left and right sides of a seat back frame (1) and extending in the vertical direction; and frame's extension sections (17b, 18) extending from the frame's side sections (15a, 17a) toward the inner side in the left-right direction. Deformable sections (17k) which deform when an impact load is applied are formed at connection sections (17x) connecting the frame's side sections (15a, 17a) and the frame's extension sections (17b, 18). The deformable sections (17k) are formed adjacent to other deformable sections (17m, 17e) having different degrees of susceptibility to deformation.
