LAMINATED STRUCTURE HAVING PIPE FOR FEEDING AND DRAINING FLUID

PROBLEM TO BE SOLVED: To provide a laminated structure allowing a pipe for feeding and draining a fluid to be fixed and connected to an end of a layered product even if it is not subjected to complicated machining particularly. SOLUTION: This laminated structure 1 is composed by stacking a plurality of plate materials 11-20 each having a fluid passage in the inside thereof to form a layered product and by connecting the cross-sectionally circular pipe 30 to an end of the layered product 10. The layered product 10 includes: a first plate material 12 having a first pipe reception groove 12a in contact with the circumferential surface of the pipe 30 from both sides at a first height position; and a second plate material 13 having a second pipe reception groove 13a in contact with the outer circumferential surface of the pipe 30 from both sides at a second height position different from the first height position. The width w1 of the first pipe reception groove 12a of the first plate material 12 is different from the width of the second pipe reception groove 13a of the second plate material 13.
