According to this relationship, the two power receiving coils 41 on the movable body 99 side do not face each other during the small separation distance DT on the substrate production line 9 side.

- “Opposite” means a positional relationship in which a part of the length LR in the moving direction of the power receiving coil 41 faces within the range of the length LT in the moving direction of the power feeding coil 31.

At this time, the two power receiving coils 41 share a magnetic flux induced by one power feeding coil 31 to be in a good power receiving state. Therefore, a larger AC power is ensured than in the positional relationship shown in FIG.

Thereafter, the power receiving coil 41 on the left side faces the feeding coil 31 of the second board production machine 92 and the power receiving coil 41 on the right side faces the feeding coil 31 of the third board production machine 93.
- the power receiving coil 41 facing the power feeding coil 31 is sequentially switched. Nevertheless, at least any one of the power receiving coils 41 always faces the power feeding coil 31 to ensure a good power receiving state.

That is, even if the line configuration of the board production line 9 is changed, the non-contact power feeding device 1 is ensured a good power receiving state without changing the configuration. Further, when the number of boards in the board production line 9 is increased to four or more modules, the length LT and the separation distance DT of the power supply coil 31 have the same value in the additional portion.

- the AC power supply 2 is provided in each of the three substrate production machines 91, 92, 93, and can operate independently of each other. Therefore, each AC power supply 2 can be reduced in size with a small capacity, and the space for mounting on the board production machines 91, 92, 93 is small. Furthermore, the AC power supply 2 can be stopped in the board production machine that is away from the moving body 99. For example, in the positional relationship shown in FIGS. 1 and 3, the third substrate production machine 93 can stop the AC power supply 2.

- DT The moving direction of the length of yl 41 and LR, the distance between each other of the power receiving coil 41 when a DR, the relationship of DT ⁇ DR, and (2 ⁇ LR + DR) relationship ⁇ LT holds.
- At least one of the power receiving coils 41 always faces the power feeding coil 31 at all times. Accordingly, at least one power receiving coil 41 can always receive a large amount of AC power while ensuring a good power receiving state. Thereby, the pulsation of the alternating current power received can be suppressed, and always stable non-contact electric power feeding can be performed.
- one of the plurality of power receiving coils 41 faces the one of the plurality of power feeding coils 31 as the moving body 99 moves, and There is a positional relationship in which the other power receiving coil 41 faces the other power feeding coil 31 among the plurality. At this time, the two power receiving coils 41 are both in a good power receiving state, and a large AC power is secured.
