- 棒状のセラミック体と、該セラミック体に埋設された、第1直線部、該第1直線部と並んで設けられた第2直線部および前記第1直線部と前記第2直線部とを繋ぐ折返し部から成る発熱抵抗体とを備えており、前記第1直線部を通り前記セラミック体の軸方向に垂直な断面を見たときに、前記第1直線部が第1長軸を、前記第2直線部が第2長軸を有する形状であるとともに、前記第1長軸に対して前記第2長軸が傾斜しており、前記第1直線部および前記第2直線部の図心が前記セラミック体の図心よりも前記第1長軸と前記第2長軸との間隔が狭まる側にずれているヒータ。
- 前記第1直線部を通り前記セラミック体の軸方向に垂直な断面を2箇所で見たときに、前記2箇所の断面のうち前記折返し部から遠い断面における前記第1長軸に対する前記第2長軸の傾きが、前記2箇所の断面のうち前記折返し部に近い断面における前記第1長軸に対する前記第2長軸の傾きよりも、大きい請求項1に記載のヒータ。
- 前記第1長軸に対する前記第2長軸の傾きが、前記折返し部から遠ざかるにつれて、大きくなっている請求項2に記載のヒータ。
- 請求項1乃至請求項3のいずれかに記載のヒータと、前記ヒータを保持する金属製保持部材とを備えたグロープラグ。
