PROBLEM TO BE SOLVED: To provide a power supply unit and a non-contact power transmission system, capable of continuing power supply to a predetermined load if a vessel is extracted from a storage.SOLUTION: A power supply unit 1 is mounted on a vessel 10 including a plate body 30, whose inside can be seen through, and a lid 20 which covers the upper part of the plate body 30 and whose inside can be seen through. The power supply unit 1 includes: a power reception coil 41 mounted on the lid 20 or the plate body 30; and a secondary battery 45 mounted on the lid 20 or the plate body 30. Power is fed to the power reception coil 41 by making conductive a power supply coil 90 provided in a non-contact manner to the power reception coil 41 outside the vessel 10, so as to charge the secondary battery 45 from the power reception coil 41.SELECTED DRAWING: Figure 1 【課題】保存庫内から容器を取り出した場合であっても所定の負荷への電力供給を継続することができる電力供給ユニット及び非接触電力伝送システムを提供すること。【解決手段】本発明は、内部を透視可能な皿本体３０と、皿本体３０の上部を覆う内部を透視可能な蓋部２０とを備える容器１０に取り付けられる給電ユニット１であって、蓋部２０又は皿本体３０に取り付けられる受電コイル４１と、蓋部２０又は皿本体３０に取り付けられる二次電池４５と、を備え、容器１０の外部において受電コイル４１と非接触に設けた給電コイル９０に通電することにより受電コイル４１に給電し、受電コイル４１から二次電池４５に充電を行うことを特徴とする。【選択図】図１
