Abstract
In a resin coating which is used in the manufacture of an LED package which is made by covering an LED element with resin that includes fluorescent substance, a light-passing member () on which the resin () is test coated for light emission characteristic measurement is carried on a light-passing member carrying unit (), a deviation between a measurement result obtained after the light emission characteristic of the light that the resin () emits, when an light source unit (), which is placed above, emits excitation light which excites the fluorescent substance, and irradiates the excitation light from above to the resin () which is coated on the light-passing member (), is measured and the light emission characteristic prescribed beforehand is obtained, and an appropriate resin coating quantity with which the resin should be coated on the LED element is derived for practical production based on the deviation.
