Wireless power transmission device for closed space

#A closed space such as a glove box, a clean room, or the like, requires high sealability to prevent leakage of substances from the inside to the outside (to deal with bacteria, toxic substances, or filth) and prevent intrusion of substances from the outside to the inside (to prevent intrusion of moisture or dust into dry and clean environment).

#Meanwhile, there is a need to supply electric power into the closed space to drive a lighting device and a storage device.

#In the related art, a power supply means for such a closed space is disclosed in Patent Documents 1 to 4.
