ABSTRACT:
An electroless plating apparatus includes: a storage tank for an electroless plating solution; a blocking member which blocks the electroless plating solution from flowing from a treatment side of a semiconductor wafer installed to the storage tank toward an opposite side to the treatment side, the treatment side being a side facing the electroless plating solution; and a solution supplier which causes the electroless plating solution to flow so that the electroless plating solution comes in contact with the treatment side of the semiconductor wafer.
