PURPOSE: A heat radiation lamp is provided to improve economic efficiency by enabling a manufacturer to simply manufacture the heat radiation lamp. CONSTITUTION: A heat radiation element(110) is heated with power applied from the outside. A terminal unit(130) transmits the power by connecting the heat radiation element. A glass tube(150) accommodates the heat radiation element and a part of the terminal unit. The terminal unit is located in the inner center of a sealing unit(170). The terminal unit seals up an end of the glass tube. The sealing unit forms a vacuum space inside the glass tube. The sealing unit includes a double glass tube(190). The double glass tube is overlapped with the glass tube. |
