Method of manufacturing light emitting device with multiple light emitting elements which are simultaneously connected to mounting board in flip chip manner

A method of manufacturing a light emitting device, includes: temporarily connecting light emitting elements to a wiring layer through connection members, the wiring layer being formed on a mounting board provided with reflectors; contacting a pressing surface of a press-bonding jig with upper surfaces of the light emitting elements and pressing the light emitting elements toward the mounting board while being heated at the same time to deform the connection members and to contact the pressing surface with tops of the reflectors; and connecting the light emitting elements to the wiring layer in a flip chip manner, wherein when the light emitting elements are temporarily connected to the wiring layer, a sum of height of a light emitting element of the light emitting elements and a connection member of the connection members is set to be larger than a height of a reflector of the reflectors.
