PROBLEM TO BE SOLVED: To provide an optical writing device which can suppress deformation and vibration of a light source substrate.SOLUTION: Spherical protrusions (SRs) 201a, 201b, 201c and through holes 204a, 204b are formed on a holder 200. Auxiliary materials 202a, 202b are fixed in the through holes 204a, 204b. The SRs 201a, 201b, 201c and the auxiliary materials 202a, 202b abut on one main surface of a light source substrate 210. The SRs 221a, 221b are formed on plate springs 220a, 220b. The SR 221a presses other main surface of the light source substrate 210 on a line segment 250 connecting an abutment position of the SR 201a and an abutment position of the auxiliary material 202a, and the SR 221b presses the other main surface in a triangle area 251 connecting the abutment positions of the SRs 201b, 201c and the abutment position of the auxiliary material 202b in a plane view. The SRs 221a, 221b press an outside of an OLED mounting area of the main surface.SELECTED DRAWING: Figure 2 【課題】光源基板の変形や振動を抑制することができる光書き込み装置を提供する。【解決手段】ホルダー２００は球状突起（ＳＲ）２０１ａ、２０１ｂ、２０１ｃ及び貫通孔２０４ａ、２０４ｂが形成されている。貫通孔２０４ａ、２０４ｂ内には補材２０２ａ、２０２ｂが固定されている。ＳＲ２０１ａ、２０１ｂ、２０１ｃ及び補材２０２ａ、２０２ｂは光源基板２１０の一方の主面に当接する。板バネ２２０ａ、２２０ｂにはＳＲ２２１ａ、２２１ｂが形成されている。平面視において、ＳＲ２２１ａはＳＲ２０１ａの当接位置と補材２０２ａの当接位置とを結ぶ線分２５０上で光源基板２１０の他方の主面を押圧し、ＳＲ２２１ｂはＳＲ２０１ｂ、２０１ｃの当接位置と補材２０２ｂの当接位置とを結ぶ三角領域２５１内で当該他方の主面を押圧する。ＳＲ２２１ａ、２２１ｂは当該主面のＯＬＥＤ実装領域外を押圧する。【選択図】図２
