PROBLEM TO BE SOLVED: To provide a pole wherein the distribution (M) of fracture bending moment of the concrete pole becomes locally large in a joint-use position (5). SOLUTION: In this prestressed concrete pole wherein a reinforcement structure is embedded in a concrete pole body, the pole body is equipped with a power-line laying position (4) wherein a power line is laid, and a miscellaneous-line laying position (5) wherein a line except the power line is laid; the pole body is elongated up to a leading end part (3) from a predetermined diameter part (d1) of a part (2) wherein the pole body comes into contact with ground, in accordance with a predetermined taper value; and a part, in the position (5), of the concrete pole is partially reinforced so that the distribution of the fracture bending moment (M) along the longitudinal direction of the concrete pole can become locally wider in the position (5).
