Abstract: A headrest includes a first configuration section comprising a hard urethane and formed with an indentation in a front face, the indentation enabling entry of a supported portion, and the supported portion being a location corresponding to an occipital bone of the head of the seated occupant; and a second configuration section comprising a soft urethane having a lower rigidity than the hard urethane, the second configuration section being provided at the indentation so as to be deformed by the supported portion. Part of the first configuration section, which is a bottom face of the indentation, is configured by a left-right pair of head support faces that support the supported portion and that are connected together at a connection location having a straight line shape. An angle formed between cross-sections of the left and right head support faces when sectioned along a plane perpendicular to the connection location is a first angle that is from 37.2° to 143°. An angle formed between a direction perpendicular to the connection location and a seat front-rear direction when viewed along a seat left-right direction is a second angle that is from 12.8° to 68.7°.
