이하에서는 이러한 면상발열체의 제조방법을 설명한다.Hereinafter, a method of manufacturing such an area heating element will be described.

먼저, 상부시트(111)와 하부시트(112) 사이에 인가된 전력에 의해 발열하는 도전선(115)을 갖는 메인부분(110a)과, 도전선(115)과 동일소재로 일체로 형성된 메인 연결단자부분(116)이 노출되게 메인부분(110a)으로부터 외부로 돌출되게 연장된 접속부분(110b)을 갖는 발열본체(110)를 형성한다.A main part 110a having a conductive line 115 that generates heat by the electric power applied between the upper sheet 111 and the lower sheet 112 and a main part 110b formed integrally with the same material as the conductive line 115, The heat generating body 110 having the connecting portion 110b extended to protrude outward from the main portion 110a is formed so that the terminal portion 116 is exposed.

다음은 전선(160)이 결합되게 제작된 클립단자(130)의 지지부분(133) 위에 접속부분(110b)에 형성된 관통홀(117)을 통해 결합핀(135)이 관통되어 삽입될 수 있게 삽입하여 안착시킨다.Next, the coupling pin 135 is inserted through the through hole 117 formed in the connection portion 110b on the support portion 133 of the clip terminal 130, .

이후, 상부 지지편(140)을 결합핀(135)을 통해 삽입하여 접속부분(110b) 상부에 안착시킨 다음, 상부 지지편(140)이 접속부분(110b)에 밀착상태로 구속되게 결합핀(135)의 상부를 하방으로 압착하여 삽입홀(142)보다 확장되게 하여 머리부(135a)을 형성한다.Thereafter, the upper support piece 140 is inserted through the coupling pin 135 and is seated on the connection part 110b.
