Temperature regulation unit and method for manufacturing temperature regulation unit

A temperature regulation unit comprising a plurality of first and second structures of porous metal which are alternately stacked on each other wherein

• each first structure of porous metal has a plurality of rod-shaped members extending parallel to each other so as to be spaced apart from each other, each rod-shaped member having a length, and a connection member connecting the respective rod-shaped members,
• each second structure of porous metal has a plurality of rod-shaped members extending parallel to each other so as to be spaced apart from each other, each rod-shaped member having a length, and a connection member connecting the rod-shaped members,
• each rod-shaped member of the first structure of porous metal and each rod-shaped member of the second structure of porous metal adjacent to the first structure of porous metal are in contact with each other along each of their respective lengths,
• the rod-shaped members of the first structure of porous metal and the rod-shaped members of the second structure of porous metal extend parallel to each other, and
• the temperature regulation unit further comprises a plurality of flow passages for a fluid each of which is formed in a gap between the respective rod-shaped members and does not communicate with another flow passage.
