Zusammenfassung:	To provide a sheet material composed of a polyamide resin which degrades water absorption while maintaining characteristic of a polyamide resin, and thereby maintains stable mechanical strength and dimension under wide environment conditions.SOLUTION: A sheet material is composed of one or more kinds of polyamide resins which have an equilibrium water absorption at a temperature of 25°C and relative humidity of 50% of 2.3% or less, and a thickness of 0.01-5.0 mm.SELECTED DRAWING: Figure 1 【課題】ポリアミド樹脂からなるシート素材において、ポリアミド樹脂の特性を保持しつつ、吸水性を低下させることで、幅広い環境条件で安定した機械強度や寸法を維持する。【解決手段】温度２５℃、相対湿度５０％における平衡吸水率が２．３％以下であり、厚みが０．０１～５．０ｍｍである１種類以上のポリアミド樹脂からなるシート素材。【選択図】図１
