Abstract
PURPOSE:To improve the tangent of a loss angle as well as high frequency characteristics of an electrolytic capacitor after lowering resistivity remarkably and improve reliability at high temperature, by using specific substances as a principal solute of an electrolyte. CONSTITUTION:7-methyl-1,14-tetradecanedicarboxylic acid having a structural formula as shown by formula (I) is used as a principal solute of an electrolyte. Then resistivity can be lowered and the tangent of a loss angle can be suppressed by taking such a step. Thus a reliable capacitor having higher performance is provided by using this driving electrolyte. Further it is preferable for the solute of 7-methyl-1,14-tetradecanedicarboxylic acid among chemical compositions of electrolyte to be within the range of 8-30wt.% and once it is less than 8wt.%, resistivity becomes large and, contrary to this, if it is exceeds 30wt.%, sparking voltage of the electrolyte goes down. Then there is a practical difficulty with both cases mentioned above.
