The identification items can be desired items such as the type (single mode and multi-mode or the like), the pore diameter size (size number) of a capillary part 11 a manufacture company abbreviation, accuracy and the propriety of an inspection. Also, in the example, for the identification symbol 40a, the character 'A' indicates the type, a numeral '1' indicates the pore diameter (mm) of the capillary part 11, the characters 'YM' indicate the manufacture company abbreviation and it is displayed that the inspection is completed by the identification symbol 40b of a broken line.
