PROBLEM TO BE SOLVED: To make a means for transporting a printed circuit board not abut with the surface of the printed circuit board, and prevent damage on the surface of a printed circuit board, in a spraying apparatus for etching a printed circuit board etc. SOLUTION: The spraying apparatus for the printed circuit board is provided with a means for horizontally transporting the printed circuit board, and a means for spraying a liquid onto the top and bottom surfaces of the printed circuit board, wherein the means for horizontally transporting the printed circuit board is a conveyer consisting of right and left rolls and has such a configuration as to arrange the right and left rolls on a bar of a ladder-shaped frame formed in approximately a V-shape while tilting them, arrange roll gears to each roll axis of the right and left rolls, and rotate the gears to rotate the right and left rolls. Thereby, the apparatus prevents the means for transporting the printed circuit board from abutting with the surface of the printed circuit board, and prevents the surface of the printed circuit board from being damaged.
