To provide a manufacturing method for a light-emitting device which easily controls and stabilizes the dispersion of a fluorescent material, improves a light extraction efficiency, and carries out two-stage sealing with a fine productivity to improve the adhesion by two-stage sealing.
The manufacturing method includes: a first step of flip mounting an LED chip 2 on the upper face of a substrate 1; a second step of sticking a pre-setting silicone sheet 4 containing a fluorescent material made of a silicone 6 dispersed with a fluorescent material 5 closely to the upper face and side peripheral face of the LED chip 2 without air therebetween and setting the silicone sheet 4; and a third step of compressively molding a translucent, pre-setting silicone into a lens covering the silicone sheet 4 when the silicone sheet 4 becomes a half-set state in the second step and setting the silicone sheet 4 and the lens at the same time to join them.
