Abstract
After displaying information () on the surface of an outer wall () of a cell structure, a portion surrounding the displayed information () is coated with a coating agent to form a region permeated with a coating agent () wherein pores () of the outer wall () are filled with the coating agent in a section of the outer wall () on which the information () is displayed. The region permeated with a coating agent () prevents a catalyst solution from exuding from the inside of the outer wall () of the cell structure. According to a method for protecting the displayed information and the cell structure of which surface information is protected by the protection method, a displayed information portion after loading catalyst components is prevented from being colored, and the displayed information can be maintained in a readable state.
