PROBLEM TO BE SOLVED: To specify the manufacturing lot number readily on the respective product, by displaying the expression which can specify the manufacturing-lot number on the surface where a bottom part and the leads of the bottom part are overlapped. SOLUTION: At the upper part of a main body 11, band-shaped anode indication, capacitance indication and rated voltage indication are displayed with white ink. Furthermore, at one of surfaces 11e where leads 12 are overlapped at a bottom part 11d of the main body 11, the indication 16 which can specify the manufacturing lot is displayed with the white ink by the same way. The indication 16 which can specify the manufacturing lot is constituted of the number of one digit meaning the manufacturing lot, one character of the alphabet expressing the manufactured month or the manufactured year and month and the number of one to two digits expressing the date. Furthermore, the number of one digit meaning the manufacturing lot is made to be the lower one digit of manufacturing-process signpost number formed in the manufacture of a capacitor. When the lot number of the product manufactured in the same day is not so many, only the lower one digit of the numbers of a plurality of the digits is displayed.
