A painting method in which a painting object (W) is connected via a holder to an arm leading end portion of a painting robot and the painting object (W) is painted by paint spraying from a spraying means while displacing the painting object (W) relative to the spraying means by an action of the painting robot ; comprising the steps of: in a preceding painting area , effecting a preceding painting on the painting object (W) by paint spraying from a preceding spraying means while displacing the painting object (W) relative to the preceding spraying means by an action of a preceding painting robot , with keeping the painting object (W) connected via the holder to an arm leading end portion of the preceding painting robot ; in a subsequent painting area (2") subsequently to the preceding painting in the preceding painting area , effecting a subsequent painting on the painting object (W) by paint spraying from a subsequent spraying means (4") while displacing the painting object (W) relative to the subsequent spraying means (4") by an action of a subsequent painting robot (6"), with keeping the painting object (W) connected via the holder to an arm leading end portion of the subsequent painting robot (6"); characterized by the steps of after completion of the preceding painting in the preceding painting area , causing the painting object (W) to be held to a transfer section located near the two painting areas (2', 2"), by an action of the preceding painting robot , releasing a connection between the arm leading end portion of the preceding painting robot and the holder with keeping connection between the painting object (W) and the holder ; retracting the arm leading end portion of the preceding painting robot from the transfer section , connecting, by an action of the subsequent painting robot (6"), an arm leading end portion of the subsequent painting robot (6") to the holder which is being held to the transfer section , with keeping the connection thereof to the painting object (W), and shifting to the subsequent painting in the subsequent painting area (2") in succession. in a preceding painting area , effecting a preceding painting on the painting object (W) by paint spraying from a preceding spraying means while displacing the painting object (W) relative to the preceding spraying means by an action of a preceding painting robot , with keeping the painting object (W) connected via the holder to an arm leading end portion of the preceding painting robot ; in a subsequent painting area (2") subsequently to the preceding painting in the preceding painting area , effecting a subsequent painting on the painting object (W) by paint spraying from a subsequent spraying means (4") while displacing the painting object (W) relative to the subsequent spraying means (4") by an action of a subsequent painting robot (6"), with keeping the painting object (W) connected via the holder to an arm leading end portion of the subsequent painting robot (6"); characterized by the steps of after completion of the preceding painting in the preceding painting area , causing the painting object (W) to be held to a transfer section located near the two painting areas (2', 2"), by an action of the preceding painting robot , releasing a connection between the arm leading end portion of the preceding painting robot and the holder with keeping connection between the painting object (W) and the holder ; retracting the arm leading end portion of the preceding painting robot from the transfer section , connecting, by an action of the subsequent painting robot (6"), an arm leading end portion of the subsequent painting robot (6") to the holder which is being held to the transfer section , with keeping the connection thereof to the painting object (W), and shifting to the subsequent painting in the subsequent painting area (2") in succession. <EOS>
