Abstract
A cushion body elastically supports a seater and is divided into three components: a central main portion and two adjacent side portions. The central main portion includes a seat pad, a substrate on the rear surface of the seat pad, a seat cover that covers the seat pad from the seat front side and has its terminal portion fixed to the substrate, and a seat heater disposed between the seat cover and the seat pad. The seat cover has a suspension portion that is suspended from the substrate through a through-hole formed in the seat pad. The substrate has a bypass hole directly facing the suspension portion, allowing a bent-back bypass portion of the seat heater to pass through and bypass the suspension portion.
