<p>PROBLEM TO BE SOLVED: To obtain a position detection apparatus which can quickly detect the position of a buried object. SOLUTION: In a position detection apparatus for a buried object, the position of the buried object which is covered with a covering object such as a wall material or the like is found in the basis of the output of a magnetic sensor which detects the magnetism of a permanent magnet installed at the buried object. A center indication part 2e which indicates that the permanent magnet is situated directly below and of a plurality of movement-direction indication parts 2a, 2b, 2c, 2d by which the direction of a dislocation from the permanent magnet is displayed as a direction in which a housing 10 is to be is installed on the surface of the housing 10 in which the magnetic sensor is built and whose rear is used as a face which is mated with the surface of the covering object. The plurality of movement-direction indication parts 2a, 2b, 2c, 2d are arranged radially around the center indication part 2e. The movement-direction indication parts display in which direction the permanent magnet is situated when the permanent magnet is not situated directly below and in which direction the position detection apparatus is to be moved so that the permanent magnet is situated directly below.</p> |
