Abstract

The present invention is directed to an electrode construction of a battery (1) in an electrical equipment. According to the present invention, at least two contacts (8a, 8b; 5a, 5b) in an electrode (4, 7) have a different shape from each other, so that the characteristic frequencies of these contacts are dif­ ferent from each other. As a result, when a contact is reso­ nating by the frequency of an oscillation applied to the elec­ trical equipment, the other contact keeps in contact with the battery (1) without resonating.
