A light-emitting device including: a substrate; LEDs arranged on the substrate in a row; electrode pad pairs each including electrode pads at opposite sides of a corresponding LED in a row direction; Zener diodes (protective elements) in one-to-one correspondence to circuits (groups) U1 to U8 each including nine consecutive LEDs, each protective element being located between adjacent electrode pads; and a sealing member sealing the LEDs, the electrode pad pairs, and the Zener diodes, wherein, in each circuit, a distance between electrode pads included in an electrode pad pair corresponding to an LED located closest to the Zener diode is the shortest, and a distance between electrode pads varies between two electrode pad pairs other than the electrode pad pair corresponding to the closest LED.
