Abstract

　ホルダ（１２）に固定された一対のレンズアレイ（１１）、（１４）を備えた光学ユニット（１）であって、主面の一部がホルダ（１２）の第一の面（Ａ）に当接した状態でホルダ（１２）に固定された第一の枠状金属板（１０）と、主面の一部がホルダ（１２）の第二の面（Ｂ）に当接した状態でホルダ（１２）に固定された第二の枠状金属板（１５）とを有する。レンズアレイ（１１）は、レンズ成形面が第一の枠状金属板（１０）の主面のうち、ホルダ（１２）の第一の面（Ａ）と当接していない領域に固定されることによって光軸方向に対して位置決めされ、レンズアレイ（１４）は、レンズ成形面が第二の枠状金属板（１５）の主面のうち、ホルダ（１２）の第二の面（Ｂ）と当接していない領域に固定されることによって光軸方向に対して位置決めされる。
