Abstract
A first side surface of post of the first stripe is formed so that a plane which is most parallel to the first side surface among low-index planes of the growing Group III nitride semiconductor is a m-plane (10-10), and a first angle between the first lateral vector obtained by orthogonally projecting a normal vector of the first side surfaces to the main surface and a m-axis projected vector obtained by orthogonally projecting a normal vector of the m-plane of the growing semiconductor to the main surface is from 0.5° to 6°. A second side surface of post of the second stripe is formed so that a plane which is most parallel to the second side surface among low-index planes of the growing semiconductor is an a-plane (11-20), and a second angle between the second lateral vector and an a-axis projected vector of the a-plane is from 0° to 10°.
