Claim:
1. A current sensor for measuring a current of a device having a frequency between a minimum frequency and a maximum frequency, the current sensor comprising: a first current path having a first end to be connected to the device such that the current to be measured flows through the first current path, the first current path including: a first magnetoelectric conversion element provided on the first current path and configured to detect a first magnetism generated by the current to be measured flowing through the first current path, the first magnetoelectric conversion element being disposed at a first position on the first flat-shaped portion having the first protrusion, wherein a minimum frequency magnetic flux density of the first magnetism generated by the current to be measured having the minimum frequency and a maximum frequency magnetic flux density of the first magnetism generated by the current to be measured having the maximum frequency are substantially the same at the first position.
