Provided is a manufacturing apparatus for manufacturing a composite stretchable member capable of improving a function of preventing cutting by reducing a defect in which an elastic member is detached from a groove of a conveying roller. The manufacturing apparatus includes a guide device that guides the two sheets and the elastic members to a bonding device. The guide device includes a guide member that guides the elastic members to respective multiple grooves on an outer peripheral surface of a conveying roller of the bonding device. The guide member is provided at its leading end with multiple guide grooves for holding the corresponding elastic members. The guide member is disposed to allow the elastic members positioned between the guide grooves and the corresponding grooves of the conveying roller to each have a length of 30 mm or less.
