The present invention provides a rigid connection structure of a bridge pier and a concrete girder capable of drastically reducing bridging cost and reducing total quantity of steel material to be used compared to a rigid-frame bridge using steel girders and capable of flexibly forming concrete girders into a shape corresponding to a bridging site without shape restriction for steel girders. In the rigid connection structure of a bridge pier 4 and concrete girder 2, a joint-equipped PC concrete girder 1 is constituted by burying a rear half part of a shaped-steel joint 3 formed of short shaped-steel respectively in both ends of the concrete girder 2 and protruding a front half part of each shaped-steel joint 3 respectively from each end face of the concrete girder 2, the respective shaped-steel joint portions 3b protruded from the respective end faces of the concrete girders 2 are supported on a bridge abutment face 12 of a bridge pier 4 while being connected to a connection stripe member 13 which arises from the bridge abutment face 12, and the respective shaped-steel joint portions 3b and the connection strip member 13 are buried in connection concrete 14 which is additionally casted on the bridge abutment face 12.
