1. A human body detecting device for detecting an approach of a human body, comprising:
- a sensor electrode provided in a housing which is a door handle of a vehicle, the sensor electrode comprising a first detecting portion and a second detecting portion for detecting the approach of the human body to the housing;
the sensor electrode being bent in U-shape so that the first detecting portion includes an outwardly extending portion extending along one side wall of the housing and the second detecting portion includes an inwardly extending portion extending along the other side wall of the housing;
a transmitting antenna provided in a space between the outwardly extending portion and the inwardly extending portion to communicate with a transmittersthe outwardly extending portion being provided at a vehicle-door side of the housing and the inwardly extending portion being provided at a side of the housing opposite the vehicle-door side of the housing;
the inwardly extending portion comprising two inwardly extending portions which extend so that a space exists between the two inwardly extending portions, with a radio wave emitted by the transmitting antenna being emitted to outside the door handle through the space between the two inwardly extending portions.
