Zusammenfassung:	To obtain a charging current in consideration of a long life of a battery 130 by suppressing temperature rise of the battery when charging the battery 130.SOLUTION: An illumination device includes: a cell 130; a lighting circuit 530 for lighting a light source unit 300 with electric power of the cell 130; and a charging circuit 520 for charging an amount of charging equal to or larger than an amount of power consumption consumed when the lighting circuit 530 lights the light source unit 300 with a very small charging current and in a charging specified time. When the battery 130 is charged, a life of the battery 130 is adapted to be not shortened.SELECTED DRAWING: Figure 3 【課題】電池１３０の充電を行う際に、電池の温度上昇を抑制し、電池１３０の長寿命化を考慮した充電電流を得る。【解決手段】電池１３０と、電池１３０の電力で光源部３００を点灯させる点灯回路５３０と、点灯回路５３０が光源部３００を点灯させたときに消費する消費電力量に相当またはそれ以上の充電量を微小な充電電流かつ充電規定時間で充電する充電回路５２０を備え、電池１３０を充電する際に、電池１３０の寿命が短くならないようにする。【選択図】図３
