Abstract
A technology is provided which makes it possible to easily produce an optical component without considerably deteriorating the optical characteristics of the optical component. The optical component includes a glass substrate, an optical member which is connected to the glass substrate, and a connecting layer used to connect a surface of the glass substrate and a surface of the optical member together. The connecting surface of the glass substrate is defined as the surface which passes light processed by the optical component, and has a roughness of approximately 3 nm to approximately 10 nm in terms of the rms value.
