The invention provides a back plate mounting structure of a seat back and a vehicle seat. The back plate mounting structure of the seat back comprises a guide wire mounted to a back plate and having awidthwise extension portion extending in a widthwise direction of a seat back frame on a front end side or a base side of the seat back frame, and a holder having a base portion rotatably supportingthe widthwise extension portion about the axis and an attachment portion attached to the seat back frame. When a force greater than or equal to a predetermined value in a direction in which the holderis detached from the seat back frame due to a force from the back of an occupant received by the back plate is applied to the holder from the widthwise extension portion, the widthwise extension portion is detached from the base portion or the holder is detached from the seat back frame, and thus, the widthwise extension portion is separated from the seat back frame.
