An electrodeless lamp is provided to improve heat radiating efficiency of a base structure by forming the base structure using a single material with high heat conductivity. An electrodeless lamp includes an envelope, a base structure(40), a rod(50), a magnetic material(60), and a coil(80). A fluorescent material is applied on an inner wall of the envelope, which includes a discharge tube at an inner center thereof. Discharge gas fills in the envelope. The base structure includes a cylinder and a mount. The cylinder is tightly contacted with a side end of the envelope. The mount is connected to the cylinder. The rod is coupled with the mount and arranged on an inner center axis of the discharge tube. The magnetic material is formed on an outer surface of the rod inside the discharge tube. The coil is arranged to be wound around the magnetic material. The cylinder and the mount are integrated into one entity. The base structure is made of a heat conductive material. A power line hole is formed on the mount of the base structure.
