Zusammenfassung:	PROBLEM TO BE SOLVED: To measure brightness without taking time, even if a sensor having no high sensitivity is used. SOLUTION: The optical measuring device 1 comprises an integral sphere 10, having an opening part 17 introducing light in the inside and an inner face 18 capable of reflecting light, a plurality of light introducing means for introducing light advanced from a plurality of measuring spots 14, 15 and 16, respectively, and a measuring instrument 11 for measuring the light amount, by receiving light reflected on the inner face 18 in the inside of the integral sphere 10.
