Summary:PROBLEM TO BE SOLVED: To provide a light-emitting device capable of radiating white light by using a single LED chip. SOLUTION: The light-emitting device includes an LED chip 10 for radiating blue light; a packaging substrate 20 where the LED chip 10 is packaged; a frame 40 for surrounding an LED chip 10 at the packaging surface side of the LED chip 10 in the packaging substrate 20; a sealing section 50 that is formed by filling a transparent resin material to the inside of the frame, seals the LED chip and bonding wires 14, 14 connected to the LED chip, and is elastic; and a dome-like color conversion member 70 that is a molding in which a yellow phosphor that excited by light radiated from the LED chip 10 and radiates yellow broad light is formed with a transparent material.
