PROBLEM TO BE SOLVED: To provide a tension structure between bridge piers capable of preventing the occurrence of noises resulting from a collision between a PC steel material and a PE pipe and to provide its construction method. SOLUTION: The tendon is so constituted that an abutting section 3 abutting the inner circumference on the PC steel material 1 is formed in the PE (polyethylene) pipe 2 inserting the PC steel material 1(PC steel strand and PC steel wire or the like) therein. The abutting section 3 makes the diameter of the PE pipe 2 as a thermoplastic pipe smaller by heating molding of the PE pipe, it is a place abutting the inner circumference of the PE pipe on the PC steel material 1 so that a plurality of places can be formed at predetermined intervals.
