To provide a heater capable of reducing a temperature difference caused between the outer peripheral side and the inner peripheral side of a rim part in a state of winding an expandable base material on the rim part.SOLUTION: A heater comprises an expandable base material windable on a rim part along the circumferential direction of the annular rim part of a steering wheel and at least one heater wire provided in the expandable base material along the longer direction of the expandable base material, wherein the expandable base material comprises a central part opposed to an outer peripheral part of the rim part in a state of being wound on the rim part along the circumferential direction and a side edge part opposed to an inner peripheral part of the rim part in a state of being wound on the rim part along the circumferential direction, and in a state of winding the expandable base material on the rim part along the circumferential direction, compression of a heater wire becomes uniform in the central part and the side edge part, and in a state before winding the expandable base material on the rim part, the heater wire is denser on the central part side than the side edge part.SELECTED DRAWING: Figure 4

    【課題】伸縮基材がリム部に巻き付けられた状態で、リム部の外周側と内周側との間に生じる温度差を低減可能なヒータを提供すること。【解決手段】ステアリングホイールの環状のリム部の周方向に沿って前記リム部に巻き付け可能な伸縮基材と、前記伸縮基材の長手方向に沿って前記伸縮基材に設けられる少なくとも1本のヒータ線とを備え、前記伸縮基材は、前記周方向に沿って前記リム部に巻き付けられた状態で前記リム部の外周部に対向する中央部と、前記周方向に沿って前記リム部に巻き付けられた状態で前記リム部の内周部に対向する側縁部とを有し、前記伸縮基材が前記周方向に沿って前記リム部に巻き付けられた状態で前記ヒータ線の疎密が前記中央部と前記側縁部とで均一になるように、前記伸縮基材が前記リム部に巻き付けられる前の状態で前記ヒータ線は前記側縁部に比べて前記中央部の方が密である、ヒータ。【選択図】図4
