Abstract
Provided is a substrate holder where an effect of a pressure of a plating solution can be suppressed. A substrate holder includes first and second holding members for sandwiching a substrate. The first holding member includes: a support base; a movable base for supporting the substrate; and a biasing mechanism disposed between the support base and the movable base, and biasing the movable base in a direction along which the movable base is separated from the support base. The second holding member includes a protruding portion brought into contact with the substrate so as to seal the substrate. A biasing force of the biasing mechanism which is applied to a region or a position of the movable base differs from a biasing force of the biasing mechanism which is applied to another region or at another position of the movable base.
