Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a light irradiation device in which illuminance due to light-emitting diodes can be measured for each vertical line, and illuminance of a line beam formed by light from these vertical lines can be maintained at a predetermined value or above, and to provide a light irradiation method.SOLUTION: The light irradiation device 10 is provided to move relatively to an integral article W, and comprises a light emission means 12 including a light-emitting diode 20 performing irradiation of light to an adhesive layer AD. A plurality of light-emitting diodes 20 are arranged on vertical lines VL and horizontal lines HL so that a line beam is formed along the horizontal lines HL by a line beam formation means 21. Illuminance of each vertical line VL is measured by an illuminance measuring means 15 so that it can be adjusted to exceed a predetermined value. Consequently, lack of illuminance is prevented from occurring in a part of the line beam LB.
