Abstract: A joined body according to the present invention includes: a main body section including a wall section that forms a passage along which a medium for accelerating heat exchange flows; and a cover configured to cover a surface of the main body section on which the passage is formed. The cover includes: a covering section provided on a side facing the main body section and configured to cover the surface of the main body section on which the passage is formed; a groove section provided on the side facing the main body section and configured to accommodate an end portion of the wall section; and a stirred joint section provided on a side opposite to a side on which the covering section and the groove section are provided. The stirred joint section is at least partly frictionally stirred by a depth reaching a bottom of the groove section from a surface on a side opposite to the side facing the main body section, and bonded to the end portion of the wall section.
