The invention provides an electrostatic capacitance type proximity sensor of a resonance mode, which can reduce the cost. The sensor electrode (11) has: an upper edge part (11a) disposed on the vehicle; a lower edge part (11b) disposed at a predetermined interval from the upper edge part (11a); and a connecting part (11c) for connecting the upper edge part (11a) and the lower edge part (11b). Thecontrol unit (32) inputs a signal for detecting a user to the electrically connected upper edge part (11a), lower edge part (11b), and connection part (11c). The lower edge part (11b) is disposed further away from the area through which the user passes than the upper edge part (11a). The installation height of the upper edge part (11a) is greater than or equal to the installation height of the lower edge part (11b).
本发明提供一种能够降低成本的共振方式的静电电容式接近传感器。传感器电极(11)具有:配置于汽车的上边部(11a);相对于上边部(11a)隔开规定间隔地配置的下边部(11b);以及将上边部(11a)与下边部(11b)相连的连结部(11c)。控制部(32)向电连接的上边部(11a)、下边部(11b)以及连结部(11c)输入用于对用户进行检测的信号。下边部(11b)配置于比上边部(11a)远离用户所通过的区域的一侧。上边部(11a)的设置高度为下边部(11b)的设置高度以上。
