Abstract
A vehicle opening-and-closing member locking-and-unlocking apparatus includes: an antenna including a series resonance circuit having a resonance capacitor and an antenna coil connected in series and an impedance regulating resistance connected in parallel to the antenna coil, the resonance capacitor side being connected in parallel to a first connecting line, the antenna coil side being connected to a second connecting line, and the antenna transmitting authentication information for locking and unlocking a vehicle opening-and-closing member to a portable device by resonance with an antenna drive signal output from an ECU via the first and second connecting lines; a human detection IC detecting contact to a human detecting area on the vehicle opening-and-closing member by the user; and a rectifier circuit configured to AC/DC convert the antenna drive signal and supply the converted signal to the human detection IC.
