Abstract
A semiconductor element includes a semiconductor layer, a first electrode and a second electrode. The first electrode and the second electrode are separated from each other on the semiconductor layer. The semiconductor layer has a first semiconductor region and a second semiconductor region. The first electrode and the second electrode are provided on the first semiconductor region. The second semiconductor region is separated from the first electrode and the second electrode. The second semiconductor region is provided to be in contact with at least a part of an end surface of the first semiconductor region. The first semiconductor region has n-type/p-type conductivity. The second semiconductor region has p-type/n-type conductivity.
