| description | A multilayer tube is provided which suppresses the amount of calcium and organic component leaching to a low level and which can be realized as a tube that has mechanical properties at 60° C. This multilayer tube includes a first polyolefin resin layer configuring the innermost layer, and a second polyolefin resin layer arranged outside of the first polyolefin resin layer; the amount of calcium leaching, measured in accordance with SEMI F-57, of the material of the first polyolefin resin layer is less than 30 μg/m2; the ratio of the thickness of the first polyolefin resin layer to the total thickness of the first polyolefin resin layer and the second polyolefin resin layer is 0.011-0.17. By means of this configuration, it is possible to suppress the amount of leaching of calcium and organic substances to a low level, and to realize a pipe having a strength that takes into account a 60° C. use environment. |
