PROBLEM TO BE SOLVED: To provide an antenna drive apparatus that has a reduced number of connection lines to a drive control section without compromising the reliability of a detection member for detecting a person's approach or contact.SOLUTION: An LF antenna 21 is driven at a resonance frequency (f1) by an AC signal supplied from a drive ECU 50 via both first and second wires W1, W2. Driven members 22, 23 are driven at resonance frequencies (f2, f3) by AC signals supplied from the drive ECU 50 via both the first and second wires W1, W2. A sensor IC 30 is driven by a DC signal supplied from the drive ECU 50 via both the first and second wires W1, W2 to detect a person's approach or contact and outputs a detection signal indicating such detection to the drive ECU 50 via the first wire W1. A stop control section 30c stops the function of the sensor IC 30 when the AC signal supplied to the LF antenna 21 or the driven members 22, 23 is detected. |
