ABSTRACT:
A corrugated synthetic resin pipe comprises a pipe wall including sectionally rectangular wall portions and sectionally circular wall portions disposed alternately in a longitudinal direction of the pipe. Each of the sectionally circular wall portions has an annular projected portion disposed at a substantially center of the sectionally circular wall portion between adjacent sectionally rectangular wall portions in the longitudinal direction, to thereby prevent parallel layout or stack layout of pipes from being disturbed.
