To provide a connector which is for use in connection of a plurality of foundation pile members such as steel pipe piles together, in the field of building/penetration, and contributes to easy and quick connection work of the foundation pile members.

The connector is fixed to connection edges 6 of the respective foundation pile members 5 each having a predetermined length, for connecting the foundation pile members 5 together, and consists of at least a pair of connector bodies 2a, 2b, and a fixing means 3 for rigidly connecting the connector bodies 2a, 2b together. Each of the connector bodies 2a, 2b is formed of a base plate 7 fixed to the connection edge 6, a connection plate 9 fixed to one surface of the base plate 7, and a connecting hole 8 bored in the connection plate 9. Then the connection plates 9 of the connector bodies 2a, 2b fixed to the connection edges 6 of the respective foundation pile members 5 opposed to each other, are engaged with each other at the time of connection, and the connector bodies 2a, 2b are rigidly connected together via the connecting holes 8 by means of the fixing means 3. In this manner the plurality of foundation pile members 5 are connected together.
