A showcase includes: a case main body; and article mounting shelves that mount articles as objects to be stored. The showcase causes the articles to be visually recognized through a customer serving face. Each of the article mounting shelves includes: a pair of brackets supported by a pair of shelf columns; and a shelf board. Each of the brackets includes locking pieces that are provided with respective notches at lower ends of predetermined areas. The showcase is supported by each of the shelf columns by causing the locking pieces to be inserted into corresponding inner face locking holes formed on an inner face of each of the shelf columns and causing lower edges of the inner face locking holes to relatively enter the notches, to cause the locking pieces to be locked to the inner face locking holes.
