PROBLEM TO BE SOLVED: To solve problems that there are constraints in increasing a heat transfer area per a volume of honeycomb/foam metal or decreasing a heat moving distance in using metallic honeycomb or foam metal of high heat transferring property to miniaturize and compactize a heat exchanger/heat exchange-type reactor, and further a temperature gradient in a reaction layer is increased when high endothermic/exothermic reaction is applied. SOLUTION: This structure uses metallic particle filling material (pressure bonding/fusion) or foam metal 9, which is filled in a clearance between an outer pipe 7 and an inner pipe 8 of a metallic double pipe. A contact area of metals is increased, and a heat transfer area per a volume of the filling material can be increased by heat transfer from an outer face of the outer pipe and an inner face of the inner pipe. Further as a moving path from the outer face/inner face exists, the heat moving distance can be reduced. This structure can be suitably used in high endothermic/exothermic reaction.
