Abstract:
A non-contact signal transmission apparatus transmits electric power and a signal in a non-contact manner via magnetic induction. The apparatus includes: a pair of annular electric power cores provided in opposing relationship to each other; a pair of electric power coils respectively provided in an annular form at one of the pair of electric power cores; and a pair of signal coils respectively provided in an annular form inside one of the pair of electric power cores. Relative permeability inside and around the signal coils is lower than relative permeability of the electric power cores.
