The purpose of the present invention is to reduce detection dead angles in the vicinity of a power transmission coil in object detection in accordance with wireless power transmission. A power transmission coil unit (210) has a power transmission coil formed by winding a conductive wire around a coil axis extending in a first direction. Each of the plurality of sensor modules (110) has a sensor having a detection range (115) in which a detection angle spread in an in-plane direction of a first plane orthogonal to the first direction is a first angle. When viewed from the first direction, the plurality of sensors are disposed in a surrounding region (215) which is a region surrounding the power transmission coil unit (210) along the outer edge of the power transmission coil unit (210). When viewed from the first direction, each of the plurality of sensors is disposed such that a second angle, which is an angle formed by a straight line overlapping the detection range (115) among a plurality of straight lines (216) constituting the outer edge of the power transmission coil unit (210) and the central axis of the detection range (115), is equal to or less than half of the first angle.

    在随着无线电力传输的物体检测中,降低送电线圈的周边附近的检测死角。本发明的送电线圈单元(210)具有绕沿着第一方向延伸的线圈轴卷绕有导线而构成的送电线圈。多个传感器模块(110)分别具有传感器,该传感器具有向与第一方向正交的第一面的面内方向展开的检测角度为第一角度的检测范围(115)。从第一方向观察,多个传感器配置于沿着送电线圈单元(210)的外缘包围送电线圈单元(210)的区域即包围区域(215)。从第一方向观察,多个传感器分别以构成送电线圈单元(210)的外缘的多条直线(216)中与检测范围(115)重叠的直线和检测范围(115)的中心轴形成的角度即第二角度成为第一角度的二分之一以下的方式配置。
