<P>PROBLEM TO BE SOLVED: To provide a method for manufacturing a heat exchanger for improving performance and being miniaturized by preventing thermal interference to a heating supercooling range without degrading rigidity of fins, and to provide an indoor unit of an air conditioner comprising the heat exchanger obtained by the method and for improving heat exchanging performance. Ž<P>SOLUTION: This method for manufacturing the heat exchanger 8 includes a process for integrally molding the fins F of a front-side heat exchanger section 8A and a rear-side heat exchanger section 8B continuously in the longitudinal direction, a process for forming heat exchange pipe mounting holes (a) of a plurality of lines to the circulating direction of the heat exchanging air, a process for forming a slit K for blocking heat between the heat exchange pipe mounting hole of the most windward-side line and the heat exchange pipe mounting hole of the most leeward-side line while they are overlapped to or communicated with each other at one end, a process for forming a cut section Kb by cutting the fins in the width direction, a process for arranging the plurality of sheets of fins, and inserting heat exchange pipes P into the heat exchange pipe mounting holes to fix the fins, and a process for folding the front-side heat exchanger section and the rear-side heat exchanger section roughly into the inverted V-shape in a side view while the cut section is located at an upper end.
