摘要：
The present invention relates to an optical element and, more particularly relates to an optical element having at least one surface in which an antireflection concave-convex structure is formed.The present invention provides an optical member in which the generation of diffraction light and reflection is sufficiently suppressed and which has a structure that can be formed in a simple manner.On a first lens surface (10) of a lens 1, an antireflection concave-convex structure (11) including a plurality of cone convex portions (12) regularly arranged is formed. The antireflection concave-convex structure (11) is for suppressing reflection of light having a wavelength equal to or larger than a cycle of the cone convex portions (12). The antireflection concave-convex structure (11) is formed so that the cycle and/or a height of the structure units differ among regions of the first surface (10).
