Abstract: A light-emitting device in which a light-emitting element, such as an LED, and an electrostatic protection element for protecting the light-emitting element from electrostatic breakdown are connected in parallel. The light-emitting device is configured such that a connection wire member of the light-emitting element and a connection wire member of the electrostatic protection element are formed of the same material; and the connection wire member of the electrostatic protection element is smaller in diameter than the connection wire member of the light-emitting element. When the light-emitting element lapses into an open-circuit state, whereby an electric current which is originally intended to flow through the element unintentionally flows through the electrostatic protection element, the connection wire member is fused by an overcurrent. Consequently, occurrence of a failure of the electrostatic protection element in a short-circuit mode can be prevented.
