Abstract
A magnetic field sensor is provided which can be easily downsized and has a capability to detect a magnetic field in the Ghz band with a high space resolution and to reduce a voltage induced by an electric field. The magnetic field sensor is composed of a first layer, a second layer and a third layer. The first layer is provided with a straight-lined conductor pattern disposed in a perpendicular manner to a mid-point of another straight-lined conductor pattern being the longest among J-shaped conductor patterns. The third layer has the same conductor pattern as the first layer. The second layer has a ladle-shaped conductor pattern disposed along the center of the width of the conductor pattern of the first layer and third layer and an L-shaped conductor pattern disposed so as to form a loop face to face with the bending section of the J-shaped conductor pattern. One end of the L-shaped conductor pattern is connected to the ladle-shaped conductor pattern and the other end is connected to end points of the straight-lined conductor patterns that are the longest among the J-shaped conductor patterns of the first layer and third layer.
