A magnetic field is formed at a predetermined region. A magnetic field formation device configured to generate a variable magnetic field at a predetermined region A includes: at least one power supplying resonator configured to generate the variable magnetic field; and power-supplying coils configured to generate an induced current in the at least one power supplying resonator, all of the power-supplying coils and the at least one power supplying resonator being disposed so that coil surfaces oppose the predetermined region A, and at least one of the power-supplying coils being disposed to have a coil surface direction which intersects with coil surface directions of the other power-supplying coils.
