Zusammenfassung:	Provided is a headrest in which a pad layer is integrally formed, including a portion with a narrow gap, between a mechanism having various types of incorporated functions and a skin member. A shock absorbing member (30) that is an injection-passage-forming member having a foaming raw material injection passage (311) formed so as to run substantially along a direction that is the vertical direction of the headrest in orientation of when a seat is attached, is set in the inside of a skin member (50), and a foaming raw material for forming the pad layer is injected through the foaming raw material injection passage (311). The configuration preferably causes the foaming raw material to spread by the foaming start time, as the foaming raw material spreads to the outer side of the headrest (10), that is, to the inner surface of the skin member (50), where the pad layer is required to be formed. Therefore, the pad layer is reliably formed between the inner surface of the skin member (50) and the outer surface of the shock absorbing member (30) when foaming starts after the foaming raw material has spread.
