Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a container manufacturing method which enables an image to be formed precisely at a high reproducibility by laser processing in a transparent or translucent part of a container without being influenced by curvature, strain, irregularity, etc. present on the surface of the transparent or translucent part.SOLUTION: A transparent or translucent part of a container having at least in a part a transparent or translucent part in contact with an outer face and having a curved part at least in a part of the transparent or translucent part is irradiated with laser beams 103 via a refractive index adjustment layer 13 consisting of a transparent or translucent liquid or elastomer in contact with the transparent or translucent part and via an optical guide member 14 in contact with this refractive index adjustment layer 13, thereby forming at least one image in the transparent or translucent part. The container is a glass, a cup, a wineglass, etc. For example, an image is formed by laser processing in the bottom of a cup made of transparent glass.SELECTED DRAWING: Figure 7 【課題】容器の透明または半透明部の表面に存在する湾曲、歪み、凹凸などに左右されることなく、その透明または半透明部の内部にレーザー加工により画像を高い再現性で精度良く形成することができる容器の製造方法を提供する。【解決手段】少なくとも一部に外面に接した透明または半透明部を有し、その透明または半透明部の少なくとも一部に湾曲部を有する容器の透明または半透明部に、その透明または半透明部に接触した透明または半透明の液体または弾性体からなる屈折率調整層１３およびこの屈折率調整層１３に接触した光導波部材１４を介してレーザー光１０３を照射することにより透明または半透明部の内部に少なくとも一つの画像を形成する。容器は、コップ、カップ、ワイングラスなどである。例えば、透明ガラス製のコップの底部の内部にレーザー加工により画像を形成する。【選択図】図７
