A light-emitting module includes a light-emitting diode (LED) package, in which an LED is implemented, and a resistor, connected to the LED in series, which is placed in the position subject to a change in temperature of the LED package. The resistor has a positive temperature coefficient. The volume resistivity of the resistor at 0° C. is preferably 2×10−8 [Ω·m] or above. The temperature coefficient of the resistor in a range of 0° C. to 100° C. is preferably 0.05 [10−3/° C.] or above.
