    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.

    Abstract: A stage includes a base material having a first surface and a second surface adjacent to the first surface, and an insulating film including a plurality of particles, each of the plurality of particles having a flat surface. The flat surface is provided along the first surface and the second surface. The base material includes a third surface in a direction 180 degrees opposite to the first surface, and a part of the flat surface included in the insulating film is provided along the third surface, and a surface obtained by extending the first surface and a surface obtained by extending the second surface intersect at 90 degrees. The base material includes a third surface in a direction 180 degrees opposite to the first surface, and a part of the flat surface included in the insulating film is provided along the third surface.

    IPC: B23K20/00

    Abstract: A joining method according to the present invention is a joining method of joining a main body which is made of aluminum or an aluminum alloy and is formed with a passage through which a medium for promoting heat exchange is circulated and a cover which is made of aluminum or an aluminum alloy and covers the passage of the main body. The method includes: a covering step of covering the main body with the cover; and a diffusion bonding step of joining the main body and the cover by diffusion bonding under a condition in which a joining temperature is 500°C or higher and 640°C or lower, and a joining surface pressure is 0.7 MPa or higher.
