Abstract
When a column is attached to an attachment location, first, a ferrule through which the column is inserted is heated and thus is fixed to the column. Then, the column to which the ferrule is fixed is attached to the attachment location. As described, when a user performs work of attaching the column to the attachment location, the ferrule is always fixed to a certain spot of the column. Therefore, it is possible to omit work of holding the ferrule such that the position of the ferrule with respect to the column does not shift when the work of attaching the column is performed. As a result, the column can be easily attached to the attachment location.
