The invention relates to a polyamine-based or polyhydric alcohol-based suppressing agent. The suppressing agent is modified by reaction with a compound that introduces a branching group into the suppressing agent before they are reacted with an alkylene oxide. The suppressing agent shows extraordinary superfilling properties, particularly when used to fill in features having extremely small aperture sizes and/or high aspect ratios.
