(57) The polishing apparatus (10) is capable of improving accuracy of polishing a work
(W). The work (W) is pressed onto a polishing cloth (11), with an elastic sheet (36),
by a pressing force generated by second pressing means (34) and applied to a carrier
(28) and inner pressure of a first fluid chamber (38) generated by a fluid supplied
thereto, so as to polish the work (W). The fluid, which has been downwardly supplied
into the first fluid chamber (38), horizontally flows outward in the first fluid chamber
(38), collides with a side wall of a concave part (23) of a board-shaped member (22)
and flows upward, and then the fluid is discharged outside from a fluid outlet (44),
thereby a fluid feeding member (31) follows movement of the elastic sheet (36) and
maintains parallel thereto, and the fluid feeding member (31) is centered in the first
fluid chamber (38).
