Nodal line semimetals, whose valence and conduction bands cross on a line in the Brillouin zone, have attracted a lot of attention as a new class of topological materials. Recently it has been reported that NaAlSi is belong to nodal line semimetals and it shows superconducting transition at 7K, which is relatively high temperature. We will present the electronic properties of NaAlSi measured by low temperature scanning tunneling microscopy.
