PURPOSE: A heater unit for generating infrared rays and a manufacturing method thereof are provided to form various shapes and to radiate infrared rays in a wide area by heating infrared ray heating coils arranged in a glass case. CONSTITUTION: A heater unit (10) for generating infrared rays comprises a glass case (20), side walls, and an accommodation room. The side walls are formed on the bottom edge of the glass case to form the accommodation room in which one side thereof is open. Guiding rods (24) are installed on the bottom at a constant interval. Infrared ray heating coils (30) are arranged zigzag using the guiding rods. A connection terminal (31) formed on both ends of the infrared ray heating coils is drawn to the outside of the side walls. The glass case and cover are fixed in a vacuum state by vacuumizing and heat-treating the inside of the accommodation room after spraying glass frit on the junction of the side walls and covering the junction with a cover (40). |
