Abstract

PURPOSE: To simplify structure and improve reliability by using a lead frame, where plural external connection terminals are arranged, and a tow-split cover material.
CONSTITUTION: Stainless lead frame 4 where many sets of four external connection terminals 4aW4d arranged at a prescribed interval are arranged into one body at a prescribed pitch with the same direction, cover materials 5a and 5b which have the one end aperture part provided with wire-nettings 6a and 6b, and coil-shaped heater 3 are prepared. Both ends of coil-shaped heater 3 are welded to the tip of external connection terminals 4a and 4d of lead frame 4, and gas sensing material 1 is inserted to coil-shaped heater 3, and the end of external lead 2 is welded to external connection terminals 4b and 4c, and after that, cover materials 5a and 5b are arranged from both side faces of external connection terminals 4aW4d and are connected to each other. As a result, gas sensing material 1 is protected mechanically, and plural explosion-proof gas sensors are formed.
