Claim 5:
6. The light emitting device according to claim 1, further comprising:
a heat sink that dissipates heat of the flat heat pipe mechanism,
wherein the heat sink is disposed on a side opposite to the light emitting substrate with the flat heat pipe mechanism interposed between the heat sink and the light emitting substrate, and dissipates heat removed from the light emitting substrate by the flat heat pipe mechanism,
the flat heat pipe mechanism is an L-shaped flat heat pipe having a first flat plate portion which is a heat input portion and a second flat plate portion which is a heat output portion,
the flat heat pipe is disposed in a state where the first flat plate portion faces the other surface side of the insulating substrate,
the cooling unit cools the flat heat pipe by applying an air flow to the second flat plate portion, and
the heat sink is disposed between the second flat plate portion and the cooling unit.
