PROBLEM TO BE SOLVED: To provide a blue color phosphor suppressing light-emitting intensity reduction during a process for producing a light-emitting device and also in driving the light-emitting device. SOLUTION: This light-emitting device is equipped with a fluorescent film containing a blue color-emitting europium-activated alkaline earth silicate phosphor expressed by (Ae)<SB>a-d</SB>(Be)Si<SB>b</SB>O<SB>c</SB>:Eu<SB>d</SB>[wherein, Ae is at least 1 kind selected from Sr, Ca and Ba; Be is at least one kind selected from Mg and Zn; (a), (b), (c) are each a=1, b=1, c=4; a=1, b=2, c=6; a=2, b=2, c=7; a=3, b=2, c=8; and (d) is 0.01≤d≤0.1].
