1. A layered body comprising
a first base material containing a phenol-based resin, a low-boiling-point aliphatic hydrocarbon (A1) having a branch and having 15 to 24 carbon atoms, and a high-boiling-point aliphatic hydrocarbon (A2) having a branch and having 25 to 35 carbon atoms, and
a second base material containing a phenol-based resin, a low-boiling-point aliphatic hydrocarbon (A1) having a branch and having 15 to 24 carbon atoms, and a high-boiling-point aliphatic hydrocarbon (A2) having a branch and having 25 to 35 carbon atoms,
wherein the first base material contains 0.5 to 3% by mass of the low-boiling-point aliphatic hydrocarbon (A1) and 0.5 to 3% by mass of the high-boiling-point aliphatic hydrocarbon (A2), and the second base material contains 0.5 to 3% by mass of the low-boiling-point aliphatic hydrocarbon (A1) and 0.5 to 3% by mass of the high-boiling-point aliphatic hydrocarbon (A2),
wherein the first base material and the second base material are adhered to each other via an adhesive containing 65 mol % or more of a butylene terephthalate unit and 5 mol % or more of a butylene isophthalate unit, and having an acid value of not larger than 100 eq/ton, a glass transition temperature of −10 to 60° C., and a specific gravity of not less than 1.20,
wherein the first base material and the second base material are the same or different,
wherein the low-boiling-point aliphatic hydrocarbon (A1) is detectable for a retention time of not shorter than 12.0 minutes and shorter than 19.1 minutes under a measurement condition 1 of pyrolysis-gas chromatography mass spectrometry (PY-GC/MS), and
the high-boiling-point aliphatic hydrocarbon (A2) is detectable for a retention time of not shorter than 19.1 minutes and shorter than 30.0 minutes under a measurement condition 1 of pyrolysis-gas chromatography mass spectrometry (PY-GC/MS), and
wherein the measurement condition 1 of pyrolysis-gas chromatography mass spectrometry (PY-GC/MS) includes, for the layered body, holding at 200° C. for 10 minutes in a PY section, holding at 40° C. for 2 minutes in a GC section, and raising a temperature to 300° C. at a temperature rising rate of 10° C./min.
