備が不要になる。2. Description of the Related Art An AC adapter is used to generate a DC power supply required for an electronic device from a commercial AC power supply. However, if there is no battery, the DC output is cut off when the commercial AC power supply is cut off. There is no problem if the electronic device has a battery backup, but in many cases the battery backup is not performed. The commercial power interruption may occur not only due to a power outage, but also due to a premature power interruption in an office and a breaker operation at home due to overuse of other home electric appliances. If the power is turned off while working with a personal computer or word processor, or while communicating with a modem or DSU, the work up to that point may be lost. For this reason, incorporating a battery into the AC adapter is a highly versatile power supply backup method. Thereby,
On the electronic device side, there is no need to prepare a battery and a space for accommodating the battery.

とは言い難かった。However, as shown in FIG. 4, in a style in which the battery 2 is simply incorporated into a conventional AC adapter and the heat-generating component 7 is cooled by the internal radiator 18, the case 16 becomes large. In addition, the performance of the battery 2 is adversely affected in terms of heat. Inevitably, heat is generated inside the AC adapter main body, and the battery 2 itself generates heat while being charged, so that the temperature of the battery 2 becomes too high and the battery performance is deteriorated. If the influence of this heat generation is to be suppressed, the parts 19 and the space 17 of the AC adapter main body must be enlarged, and the case 16 must be enlarged, which is disadvantageous in terms of size and weight. If it becomes heavier and heavier, it is inconvenient to carry it. There is also a method of lowering the temperature by opening ventilation holes in the AC adapter, but spilling metal staples, clips, solder debris, or liquids such as water or coffee may cause a short circuit in the internal circuit or cause a failure. In some cases, safety was not perfect.
