A lamp tube structure includes a first end cap, a second end cap, a heat sink holder, a light emitting element array and a lamp cover. The first end cap includes a pair of electrical terminals and a first insulating portion. The electrical terminals are integrated into the first insulating portion by insert molding, and one end of each electrical terminal is protruded from an outside of the first insulating portion. The second end cap includes a grounding terminal and a second insulating portion. The grounding terminal is integrated into the second insulating portion by insert molding, and one end of the grounding terminal is protruded from an outside of the second insulating portion. The light emitting element array is disposed on top surface of the heat sink holder. A bottom surface of the lamp cover is fixed on the heat sink holder for receiving the light emitting element array.
