A ferrule container 1 is provided with a ferrule accommodating part 11 and a first column guide part 12. A ferrule is accommodated in the ferrule accommodating part 11. The first column guide part 12 guides a column so as to insert the column into the ferrule accommodated in the ferrule accommodating part 11. Guiding of the column by the first column guide part 12 enables the column to be smoothly and reliably inserted into the ferrule accommodated in the ferrule accommodating part 11. Consequently, unlike a case in which an operator inserts a column while pinching a ferrule with hand, the work of inserting a column into a ferrule can easily be performed.
