PROBLEM TO BE SOLVED: To conduct a dipping step for manufacturing a product having high reliability. SOLUTION: The method for manufacturing the circuit board comprises the steps of relaxing a long-sized board 10 conveyed by first and second rollers 20, 22 between the rollers 20 and 22, dipping the board in a liquid 30 so that at least one of the rollers 20, 22 is a drive roller 20, disposing a sensor 50 for detecting a position of the board 10 in a liquid tank 32 and a liquid jet port 40, and regulating the looseness of the board 10, thereby controlling the conveying route of the board 10 in the liquid.
