PURPOSE: To obtain a synthetic resin-made corrugated pipe with a plain end part having superior cut-off properties and a good connecting workability.

CONSTITUTION: A synthetic resin-made corrugated pipe is so structured as to have a plain inner peripheral surface 1 and a recessed and projected corrugation on an outer peripheral surface, on which recessed parts 2 and projected parts 3 having hollow parts 4 are alternately formed. On either or both of end parts of the pipe, a flat same-outer diameter periphery 6 having a thickness at least higher than the projected part 2 and a length at least one pitch, pref. two or more pitches, of the recessed and projected corrugation from the end and a plain end face 7 orthogonally connected to the same-outer diameter periphery 6 are formed out of a thermosetting resin 5 composed of a reactive curable filler.
