To provide a film heater that can be easily adhered to an adherend that has irregularities and does not contain bubbles that cause defects in appearance or damage without impairing the design of the adherend to be heated, and therefore, the film heater has high formability, high mechanical strength, and excellent adhesion to an adherend.SOLUTION: In a film heater, a conductive pattern 2 made of conductive wires is provided on one surface of a support sheet 1 made of a transparent thermoplastic resin sheet, and the other surface of the support sheet has irregularities, and the conductive pattern includes connection terminal portions 21a and 21b, lead wires 22a and 22b extending from the connection terminal portions, and a heater portion 23 continuing from the lead wires.SELECTED DRAWING: Figure 1 【課題】加熱対象となる被着体の意匠性を損なうことなく、また、外観不良や破損等の原因となる気泡を含みにくく、凹凸があるような形状の被着体に対しても簡単に貼着することができ、成形性、機械的強度が高く、被着体に対する接着性に優れたフィルムヒータを提供する。【解決手段】透明な熱可塑性樹脂シートからなる支持シート１の一方の面に導電線からなる導電性パターン２が設けられ、支持シートの他方の面は凹凸を有し、導電性パターンが、接続端子部２１ａ、２１ｂと、接続端子部から延びたリード線２２ａ、２２ｂと、リード線から続くヒータ部２３とを有するフィルムヒータ。【選択図】図１
