PURPOSE:To provide a gas heating device which is used for an emission gas controlling secondary air supply device for an internal combustion engine and has high reliability and productivity. CONSTITUTION:In each end of a heat generator 11, a flat part, 10a is formed, while a flat part, is formed in a part of a cylindrical pipe 10, and these flat parts are arranged opposingly, and then, the heat generator 11 and the pipe 10 are integrally fixed together by means of fixing members 12, 13. In this way, positioning of the heat generator 11 to the pipe 10 in insertion of the heat generator 11 is facilitated. |
