PROBLEM TO BE SOLVED: To provide a lamp socket unit which suppresses an abnormal temperature increase and improves durability, a lighting device, and a lighting apparatus. SOLUTION: The lamp socket unit includes a first conductive plate 2 with which a lamp pin 230 contacts and is connected, a second conductive plate 3 which has a terminal 30 connected to a feeder cable for supplying power to a lamp and a contact 31 in contact with the first conductive plate 2, and a socket body housing the first conductive plate 2 and the second conductive plate 3. The contact 31 of the second conductive plate 3 is formed of a bimetal which is deformed into a shape that does not contact with the first conductive plate 2 when a temperature is equal to or higher than a given temperature, and deformed into a shape that contacts with the first conductive plate 2 when the temperature is lower than the given temperature.
