Integrated connector and heat exchanger including the same

A method of manufacturing an integrated connector, the method comprising:

• a connector main body forming step of integrally forming, at one side, a first flange portion, in a shape in which a pipe is folded outward so that the folded portions overlap each other, and forming, at the other side, a second flange portion, in a shape in which the pipe is folded outward so that the folded portions overlap each other, based on a central portion of the pipe based on a longitudinal direction by pressing the pipe from two opposite sides based on the longitudinal direction of the pipe in a state in which the central portion of the pipe, which is a forming object, based on the longitudinal direction is fixed, such that a first pipe portion integrally extends outward from the first flange portion in the longitudinal direction, and a second pipe portion integrally extends outward from the second flange portion;
• and
• a cap coupling step of press-fitting a cap into a connector main body so that an interior of the connector main body is blocked by the cap, and connection is blocked.
