PROBLEM TO BE SOLVED: To provide an assembling method for an optical module (optical receiver) such that even if an optical plane is inclined to a predetermined optical axis, the optical plane can have its angle easily adjusted.SOLUTION: An assembling method is an assembling method for an optical module comprising a light input port fitted to one end face of an enclosure, and an optical component arranged in the enclosure and having an optical plane having a predetermined angle other than 0° and 90° to an optical axis of the light input port. The method includes the steps of: mounting an alignment jig 60, having a pair of mutually parallel surfaces 61, 62 and a reference surface 63 at a predetermined angle θ to the surface 61, on an alignment rotary stage 70 while pressing the surface 61 against a mounting reference surface 71 provided on the alignment rotary stage 70; rotating the alignment rotary stage 70 to set the reference surface 63 in a predetermined direction; mounting an enclosure on the alignment rotary stage 70 instead of the alignment jig 60; and arranging an optical component in the enclosure with the optical surface in the predetermined direction.SELECTED DRAWING: Figure 6 【課題】光学面が所定の光軸に対して傾いている場合であっても、光学面の角度調整を容易にできる光モジュール（光受信器）の組立方法を提供する。【解決手段】この組立方法は、筐体の一端面に取り付けられた光入力ポートと、筐体内に配置され、光入力ポートの光軸に対して０°及び９０°以外の所定角度を成す光学面を有する光部品とを備える光モジュールの組立方法であって、互いに平行な一対の面６１，６２と、面６１に対して所定角度θを成す基準面６３とを有する調芯治具６０を、調芯回転ステージ７０上に設けられた搭載基準面７１に面６１を押し当てつつ調芯回転ステージ７０上に搭載する工程と、調芯回転ステージ７０を回転させて基準面６３を所定方向へ向ける工程と、調芯治具６０に代えて筐体を調芯回転ステージ７０上に搭載する工程と、光学面を所定方向に向けた状態で光部品を筐体内に配置する工程とを含む。【選択図】図６
