Abstract: The alternating current light-emitting device includes: a light-emitting module having a substantially-transparent molded piece, three or more LEDs disposed so as to be linearly lined up on the substantially-transparent molded piece with a lead frame interposed therebetween and connected in series, and a resin member formed so as to cover each of the LEDs in a direction in which the LEDs are lined up; a main substrate including the light-emitting module disposed on a front surface thereof; and a rectifier element and a current-limiting element provided on the main substrate.
