PROBLEM TO BE SOLVED: To provide a capacitance detection line and its application capable of preventing a malfunction and obtaining a superb detection accuracy by being capable of fixing a distance between two electrodes at a constant state.SOLUTION: A capacitance detection line includes: a first electrode line 1; a second electrode line 2; a temperature detection line 3; and a core wire 4. The first electrode line 1, the second electrode line 2, and the temperature detection line 3 are aligned and wound on the core wire 4. At least two of the first electrode line 1, the second electrode line 2, and the temperature detection line 3 are covered by insulation coating 5. The capacitance detection line 10 detects a capacitance value between the first electrode line 1 and the second electrode line 2. The capacitance detection line 10 forms an outer cover layer 7 on the circumference. A capacitance detection unit installs the capacitance detection line on a base material. A human body detector for detecting a human body approach by a change of a capacitance value detected by the capacitance detection line and a seat with a seating detection function for detecting the presence or absence of the seated human being are provided.SELECTED DRAWING: Figure 1 【課題】２つの電極間の距離を一定状態で固定できることにより、誤動作を防止でき優れた検出感度を得ることが可能な静電容量検知線と、その応用品を提供すること。【解決手段】第一の電極線１と第二の電極線２と温度検知線３と芯線４を有し、上記第一の電極線１、上記第二の電極線２及び上記温度検知線３が引き揃えられて上記芯線４上に巻装されており、上記第一の電極線１、上記第二の電極線２及び上記温度検知線３の少なくとも２本が絶縁被膜５により被覆されており、上記第一の電極線１と上記第二の電極線２間の静電容量値を検知する静電容量検知線１０。外周に外層被覆７が形成されている静電容量検知線１０。上記静電容量検知線が基材上に配設されている静電容量検知体。上記静電容量検知線により検知された静電容量値変化により人体接近を検出する人感検知器及び着座者有無を検出する着座検知機能付き座席。【選択図】 図１
