PROBLEM TO BE SOLVED: To provide a squeegee for printing a cream solder capable of uniformly and accurately controlling an amount for printing the cream solder regardless of whether it is in the neighborhood of a projected part when a metal mask formed with the projected part is laminated on a circuit board and the cream solder fed on this metal mask is screen-printed on the circuit board, and to provide a method for printing the cream solder. SOLUTION: A plurality of slits 6 are formed on the apex part of the squeegee 5 being brought into close contact with the metal mask 3, and each of the slits 6 is one by one independently deformable. It is possible thereby that when the squeegee 5 is moved along a flat part of the metal mask 3, the squeegee 5 can be brought into close contact with the flat part without deformation, and on the other hand, the projected part 3a can be climbed over by the deformable part of the squeegee 5 which can freely deform one by one by making the slit 6 as a boundary, and the cream solder 4 can be printed even through an opening part 3b adjoining the projected part 3a in the similar way to a case through an opening part separated from the projected part 3a.
