Abstract: 본 발명은 황토에 숯과 옥 분말 가루를 섞어 바둑알 형태로 성형하여 건조시키고, 그 표면에 세라믹 코팅한 후 구워서 된 원적외선 발산부재를 매트 표면이나 내부 상층에 부착시켜 사용시 원적외선이 다량으로 발산되도록 함으로써 사용자의 신체에 원적외선 방사와 동시에 전열 치료, 온열 치료 등의 효과를 갖도록 한 황토를 이용한 원적외선 방사 매트의 구조에 관한 것이다. 
     기존의 원적외선이 방사되는 황토 분말, 옥 분말, 숯 덩어리 등을 넣은 매트는 사용시 파손되어 분말 가루가 유출되는 것을 방지하기 위해 매트 내부에 분말 가루가 내장되는 별도의 공간부를 형성하고 이를 비닐지 또는 내자(인조 가죽)로 포삽되도록 외피를 형성함으로써 원적외선의 방출량이 저하되는 단점이 있는 반면에 제작 단가는 상승되어 가격이 비싼 문제점이 있었다. 
     본 발명은 이와 같은 문제점을 감안하여 발명한 것으로서, 황토 분말과 소량의 숯 분말, 옥 분말을 혼합하여 구슬 형태의 황토볼(2a)(2b)(2c)(2d)을 만든 다음 상하부를 압착시켜 바둑알 형태로 성형한 황토알(2a')(2b')(2c')(2d') 표면에 세라믹 코팅(3)한 원적외선 발산부재(2)를 형성하여 전기 매트, 전기 장판, 전기 요, 찜질 팩, 물리 치료 온열 매트 등의 내부 상층부 또는 표면에 부착시켜 사용시 전기의 열에 의하여 원적외선이 대량으로 방사되도록 함으로써 신진대사를 원활히 함과 동시에 사용자의 신체에 황토알이 지압되어 경혈을 눌러 자극하므로 혈액 순환을 촉진시키고 전열 및 온열 치료 효과를 가질 수 있도록 한 것이다.
