An objective is to provide a compact self-ballasted fluorescent lamp which can reduce occurrence of a short circuit without protecting lead wires extending from each end portion of a spiral arc tube. To achieve the objective, a pair of connection pins is provided on a circuit board of the compact self-ballasted fluorescent lamp, near a periphery of the circuit board so as to oppose another pair of connection pins formed near the periphery. In this way, the pairs of connection pins can be respectively provided directly above the end portions of the spiral arc tube. Thus, lead wires extending from each of the end portions can be connected to a corresponding one of the pairs of connection pins with a relatively short distance. This prevents the lead wires from being in contact with the circuit board, thereby reducing occurrence of a short circuit.
