A first corrugated strip is fixed between first and second adjacent tubes of the heat exchanger such that the first corrugated strip is kept in a straight shape by the first and second tubes. The straightening member is detached from the first corrugated strip by breaking the first bridge member such that there is provided a first sandwiched structure having the first corrugated strip fixed between the first and second tubes.
