Abstract

A seed crystal substrateincludes a base bodyand a plurality of rows of stripe-shaped seed crystal layersformed on the base body. An upper faceof the seed crystal layeris (11-22) plane, a grooveis formed between the adjacent seed crystal layers, and a longitudinal direction of the grooveis a direction in which a c-axis of a crystal forming the seed crystal layer is projected on the upper face. A nitride of a group 13 element is formed on the seed crystal substrate.
