摘要：
A piston includes a piston body, an elastic adhesive layer, and a low thermal-conductivity sheet. The piston body has a piston top surface facing a combustion chamber, and exhibits a first thermal conductivity. The elastic adhesive sheet is formed on the piston top surface of the piston body, and includes a heat resistant resin. The low thermal-conductivity sheet is formed on the elastic adhesive layer, and exhibits a second thermal conductivity being lower than the first thermal conductivity of the piston body and falling in a range of from 5 or more to 40 W/m·K or less.
