PROBLEM TO BE SOLVED: To provide a bulb type lighting device which effectively discharges heat generated by a luminous body.SOLUTION: A bulb type lighting device 10 includes: a luminous body 12 including an LED 11; a cover member 15 which covers the luminous body 12; and a radiator 20 to which an opening end part 16 of the cover member 15 is attached, the radiator 20 which discharges heat generated by the luminous body 12. A heat transmission part A70, which has good thermal conductivity and is formed by a material having an elastic modulus smaller than elastic moduli of a luminous body attachment part 22 and the radiator, is formed between the luminous body attachment part 22 and the radiator 20. |
