PROBLEM TO BE SOLVED: To solve the problem of a workman having to watch the direction of connection (polarity) carefully, when an aluminum electrolytic capacitor is connected, and long man-hours are needed for ascertaining the connections of the capacitors, so that productivity is reduced. SOLUTION: An aluminum electrolytic capacitor mounting board and an aluminum electrolytic capacitor mounting fitting are structured so that a part of the capacitor mounting board is brought into contact with a part of the capacitor-mounting fitting, to make an electrolytic capacitor unable to be connected, when the electrolytic capacitor is connected in reverse polarity. Or the mounting fitting is made to be bilaterally asymmetrical, so that the electrolytic capacitor connection cannot be made, when it is connected reverse in polarity.
