A capacitive wireless power transfer coupler, includes: a coupler transmitting side, including two electrode plates arranged in a same plane, a shielding plate parallel to the electrode plates, and a filling dielectric between each of the electrode plates and the shielding plate; a coupler receiving side, having a same structure as the coupler transmitting side. A side provided with the electrode plates of the coupler transmitting side faces a side provided with the electrode plates of the coupler receiving side, and power transfer is achieved between the two sides through a transfer dielectric, where a relative dielectric constant of the filling dielectric is less than a relative dielectric constant of the transfer dielectric. The issues of increased coupler volume, limited improvement in the capacitive coupling coefficient, and low efficiency of power transfer of the existing capacitive coupler, can be solved.
