PURPOSE: A bellows type hose is provided to quite freely vary shapes of a channel which guides the flow of a fluid according to the use purpose. CONSTITUTION: The bellows type hose which quite freely varies a type of a channel guiding the flow of a fluid according to the use purpose is manufactured by continuously extrude-molding a mountain(3) and a valley(4) by making the length ratio of both sides different from each other on the basis of a vertex of the mountain and remarkably prevents the defective rate by forming a connecting line(G2), which is placed on the upper and the lower area to connect the vertex of the mountain on the basis of the central shaft of the hose, inclined to a central shaft(H).
