Zusammenfassung:	PROBLEM TO BE SOLVED: To realize a door with improved dimensional accuracy with a simple manufacturing process at a low cost.SOLUTION: A door includes vertical cores (1), horizontal cores (2), and a center core (4), each of the vertical cores (1) being formed of a single member, each of the horizontal cores (2) being formed of a single ember whose partial portion extends such that its horizontal opposite ends abut with the respective vertical cores (1) and whose center portion (2a) has a concave shape, the center core (4) being formed with a first step (4c-1).SELECTED DRAWING: Figure 2 【課題】寸法精度が向上したドアを、簡易な製造工程・低コストで実現する。【解決手段】縦芯（１）と横芯（２）と中芯（４）とを備えており、縦芯（１）は単一の部材からなり、横芯（２）は、単一の部材からなる一部の部位の水平方向の両端が縦芯（１）と当接する位置まで延びているとともに中央部（２ａ）が凹形状となっており、中芯（４）には第１段差（４ｃ−１）が形成される。【選択図】図２
