PROBLEM TO BE SOLVED: To provide an aligner capable of eliminating failure partially caused on a conductor pattern on a printed circuit board due to post-stages. SOLUTION: In this aligner (100) to form a circuit pattern drawn on a mask (20) on a board (10) by using light sources (U1, U2...) including a plurality of light emitting parts respectively radiating light toward the board (10), light quantity data showing a relationship between positions where the respective light emitting parts radiate the light and light quantity to be outputted by the light emitting parts is preserved in a storage means (120) on the basis of post-stage characteristics information showing, for every different area on the board, the characteristics of the circuit pattern on the board to which the post- exposure processing is applied. Then, the light quantity of each of the light emitting parts is controlled on the basis of the light quantity data stored in the storage means. |
