Electronic structures derived from a local defect in graphene play important roles in various engineering fields. We used scanning tunneling microscopy to observe a monolayer nanographene sheet, which was cleaved from a graphite surface. We focused on a unique rectangular-like lattice and investigated its characteristics in detail. Moreover, the electronic structures of graphene nanoribbons were calculated based on first principles, which unveiled the origin of the rectangular-like lattice.
