Abstract
A magnetic sensor includes a sensor chip mounted on a substrate such that an element formation surface thereof is perpendicular to the surface of the substrate and a magnetism collecting member mounted on the substrate such that a surface thereof faces the element formation surface. The magnetism collecting member has a surface positioned on the side opposite to the surface, and both the surfaces are flattened. This reduces a gap between the element formation surface and the magnetism collecting member and reduces variations among products. In addition, since the surface is also flattened, the magnetism collecting member has no directionality with respect to the sensor chip when it is mounted on the substrate, so that working efficiency during assembly can be improved.
