PROBLEM TO BE SOLVED: To provide a joint structure of a steel pipe sheet pile, which can achieve a reduction in construction cost and the shortening of a construction period by securing proper constructibility and stable quality and which can increase shearing strength of a joint portion; and to provide a steel pipe sheet pile foundation. SOLUTION: An L-L joint structure is employed for female and male joints 5 and 6. This enables sure excavation of sediment in first and second filling spaces A and B of the joint portion 3, enables the sure cleaning of the insides of the spaces A and B, and enables the insides of the spaces A and B to be solidly filled with a filler 7. Additionally, a protrusion is formed on the leg portion 61 of the male joint 6, and a steel plate 8 with a protrusion is provided between the pair of female joints 5, so that the filler 7 in both the first and second filling spaces A and B can be restrained.
