PPROBLEM TO BE SOLVED: To provide a reinforcing method for a steel pipe member having a corroded part, which can reliably and easily reinforce the corroded part of a steel pipe member by covering and fastening the corroded part with a band from the outer circumference of the steel pipe member to press the member from its entire circumference toward the center. PSOLUTION: The reinforcing band A comprising two plate bodies 1 curved along the outer circumference shape of the steel pipe member B are covered on the outer circumference including the corroded part of the steel pipe member B. Plural pairs of bolt holders 2 are provided substantially at a right angle to the end fringes of the plate bodies 1 at an interval along the end fringes, provided on the outer face of the end fringes where each plate body 1 abuts on the adjacent plate body 1. Pairs of bolt holders 2 have respective bolt holes of a fixed length, and the respective bolt holes which are opposed to each other are formed to be positioned on the same axial line. Each bolt 4 is inserted through each bolt hole of the pairs of bolt holders 2, and each nut 5 is screwed to each bolt 4 end part to be fastened thereto, thereby securing the reinforcing bands A comprising the two plate bodies 1 to the steel pipe member B.
