    • PROBLEM TO BE SOLVED: To provide a holder with which a heat exchanger in which the interval between insertion pipes is reduced can be manufactured, and a device for manufacturing the heat exchanger. SOLUTION: The holder has a plurality of pipe abutting members 3f which can externally fit a mandrel for expanding the pipes in a free reciprocating motion and are free to expand or contract radially in directions intersecting the longitudinal direction of the pipes. The outer face of the pipe abutting member 3f is provided with a slant 3b. The holder 3 for the insertion pipes in the heat exchanger radially expands or contracts each of the pipe abutting members 3f via a sliding means which slides on the slant 3b in free reciprocating motions in the longitudinal direction of the pipe. The holder comprises a plurality of slit-like clearances 3a of a given width 3u which are provided in the longitudinal direction, and is shaped so that the slit-like clearances 3a gradually expand from the given width 3u at a given place to an increased width 3x toward the opening of the pipe.
