Abstract
In a wiring pattern formed on a printed circuit board, a current detection pattern having a predetermined area is formed in the wiring pattern for detecting a current, which flows to a subject body for current measurement, based on magnetic flux density generated by the current. The current detection pattern is formed of a same material as the wiring pattern. An excitation current is supplied to the current detection pattern for detecting the magnetic flux density. An output voltage outputted from the current detection pattern in correspondence to the excitation current and the magnetic flux density is measured. The current flowing to the subject body is calculated based on the magnetic flux density calculated from the excitation current and the output voltage.
