PURPOSE: A power supply device of a fishing lamp is provided to reduce oil cost of a generator by using a LED lamp of for the direct current from a storage battery. CONSTITUTION: A DC power supply connection part(15) is connected to a fishing lamp(10) for the DC power supply. A storage battery(20) supplies the DC power supply to the DC power supply connection part of the fishing lamp. A rectifier(30) changes the AC power source provided from outside into the DC power supply. An AC power source connecting part(35) supplies the AC power source provided from outside to the rectifier. The outside alternating current selectively charges the storage battery. An aerogenerator generates the DC power using wind force. A DC power supply connection part(45) supplies the DC power supply of the aerogenerator to the storage battery.
