Summary:To provide an optical writing device which can secure the positioning accuracy at the joining and suppress the ghost light, an image formation apparatus having the optical writing device, and a manufacturing method of the optical writing device.SOLUTION: An optical writing device includes a first base material made of a lens array 12 and a second base material made of a light-emitting substrate 11 or the lens array 12. At least one of the first base material and second base material is a transparent body. Each of the first base material and second base material is formed with junctions (junctions 12d, 11d) in a joint portion with another member. The junction includes: metal layers (metal layers 12a, 11a); intermediate layers (intermediate layers 12b, 11b) for providing the peak of the total transmittance of the junctions to the first wavelength band; and positioning markers (markers 12c, 11c). The first base material and second base material are joined through the metal layers. A light-emitting element emits the light in the wavelength band outside the first wavelength band.SELECTED DRAWING: Figure 6 【課題】接合時の位置合わせ精度の確保とゴースト光の抑制とを両立させることが可能な光書込装置、当該光書込装置を備える画像形成装置及び当該光書込装置の製造方法を提供する。【解決手段】レンズアレイ１２からなる第１基材と、発光基板１１又はレンズアレイ１２からなる第２基材と、を備える。また、第１基材及び第２基材の少なくとも一方は透明体であり、第１基材及び第２基材の各々は、他方の部材との接合部分に接合部（接合部１２ｄ、１１ｄ）が形成され、接合部は、金属層（金属層１２ａ、１１ａ）と、第１波長帯域に接合部の合計透過率のピークを持たせるための中間層（中間層１２ｂ、１１ｂ）と、位置合わせ用のマーカー（マーカー１２ｃ、１１ｃ）と、を含んで構成され、第１基材及び第２基材は、金属層を介して接合され、発光素子は、第１波長帯域外の波長帯域の光を出射する。【選択図】図６
