|Applicants:||USHIO DENKI KABUSHIKI KAISHA
|Title:||OPTICAL MEMBER AND OPTICAL IRRADIATION DEVICE|
[Problem] To provide a structure such that the shearing of a bonding agent due to the difference between the linear expansion coefficients of a holder made of a metal material and an optical element can be prevented for an optical member in which the optical element is fixed to the holder with the bonding agent, while suitably maintaining the relative positional relationship between the optical element and the holder. [Solution] The bonding agent is filled in recesses formed in the flat surface of the holder onto which the optical element is mounted, and the bonding agent fixes the optical element to the holder.
