To provide a high impedance substrate which has a large ratio band in a low frequency band, and at the same time, is thin enough to be mountable on an electronic device.
The high impedance substrate has: a metal plate (1) as a ground plane; a resonant circuit layer including at least two resonant circuits (2, 3) which are connected through a connection unit (4) with a distance t from the metal plate, and arranged adjacently in the same height with a distance g; and a magnetic material layer (5) arranged between the metal plate and the resonant circuit layer with a distance h from the resonant circuit layer. It is characterized that the distance t between the metal plate and the resonant circuit layer is 0.1 mm or more, and 10 mm or less; the distance g between adjoining resonant circuits in the resonant circuit layer is 0.01 mm or more, and 5 mm or less; and the distance h between the magnetic material layer and the resonant circuit layer is in a range expressed by a formula (1): g/2ht/2.
