PROBLEM TO BE SOLVED: To provide a vehicular door handle device capable of further downsizing an antenna.SOLUTION: A vehicular door handle device is configured such that a LF antenna 21 is driven by AC voltage supplied from a drive ECU 50, and a sensor IC 30 is driven by DC voltage supplied from the drive ECU 50. The sensor IC 30 includes: a power supply terminal 34 and a ground terminal 35 connected to a first electric wire W1 and a second electric wire W2, respectively; a detection signal output terminal 33 that is connected to the first electric wire W1 and outputs a negative detection signal showing the existence of detection of a person's access or contact; and an antenna drive detection terminal 36 connected to the first electric wire W1. The vehicular door handle device comprises: a DC cutting capacitor 44 having both terminals connected to the detection signal output terminal 33 and the antenna drive detection terminal 36, respectively; and a resistor 43 having both terminals connected to the antenna drive detection terminal 36 and the ground terminal 35.SELECTED DRAWING: Figure 2

    【課題】アンテナをより小型化することができる車両用ドアハンドル装置を提供する。【解決手段】駆動ECU50から供給される交流電圧によってLFアンテナ21が駆動され、駆動ECU50から供給される直流電圧によってセンサIC30が駆動されるように構成されており、センサIC30は、第1の電線W1及び第2の電線W2にそれぞれ接続された電源端子34及びグランド端子35と、第1の電線W1に接続されて人の接近又は接触の検知の有無を表す負極の検知信号を出力する検知信号出力端子33と、第1の電線W1に接続されたアンテナ駆動検知端子36とを有し、検知信号出力端子33及びアンテナ駆動検知端子36に両端子がそれぞれ接続されたDCカットコンデンサ44と、アンテナ駆動検知端子36及びグランド端子35に両端子がそれぞれ接続された抵抗43とを備える。【選択図】図2
