Abstract
To achieve sensitivity not deviating in any of XYZ directions. A three-axis antenna with a cross-shaped core (2) having a pair of X-axis arms (22a, 22b) projecting in the X-axis direction in an orthogonal coordinate system and a pair of Y-axis arms (23a, 23b) projecting in the Y-axis direction orthogonal to the X-axis direction, and having Z-axis winding wire (26) provided in a substantially rectangular frame shape, outside the head sections of the X-axis arms (22a, 22b) and the head sections of the Y-axis arms (23a, 23b). The Z-axis winding wire is housed in a case having the bottom so as to cover the entire parts of head surfaces of the X-axis arms (22a, 22b) and of head surfaces of the Y-axis arms (23a, 23b).
