Abstract
A current sensor includes a plurality of unit groups mounted in a first case and a current sensor includes a first case that is made of a resin and includes a first opposing part, a second case that is made of a resin and includes a second opposing part, a substrate mounted in at least one of the first case and second case, and a plurality of unit groups mounted in the first case and second case, each unit group measuring an induced magnetic field. second case, each unit group measuring an induced magnetic field. Each of the plurality of unit groups includes one or more measurement units arranged in a second direction. A current path and a first magnetic shield, each of which is formed integrally with a first opposing part, are positioned so as to be separated by a first distance. In all unit groups, all first distances are substantially the same. The current path and a magneto-electric conversion element, which is formed integrally with a second opposing part, are positioned so as to be separated by a second distance. In all measurement units included in a unit group shared among them, all second distances are substantially the same. The second distance differs for each unit group. The thickness of the first opposing part in a first direction is substantially constant. The thickness of the second opposing part in the first direction is substantially constant.
