A pipe joint structure comprises a joint body (1) equipped with a male thread and also comprises a cap nut (3) which is engaged with the male thread (2) of the joint body (1), and the pipe joint structure used is for the connection of an aluminum pipe (4). The pipe joint structure has a sleeve (7) for compression and deformation. The sleeve (7) is received in the inner receiving space (10) of the cap nut (3) and has a peripheral groove (9) in the outer peripheral surface (8) thereof. The sleeve (7) receives axial compression force from both the joint body (1) and the cap nut (3) when connecting the cap nut (3) and the male thread (2) of the joint body (1) by threads. As result, thin- a a walled section (13) at the bottom of the peripheral groove is plastically deformed radially inward, bites into the inserted aluminum pipe (4) from the outer peripheral surface (14) side thereof, and retains the aluminum pipe (4).
