Summary:To provide a chuck member capable of securing conductivity while improving endurance.SOLUTION: A chuck member 90 holds a substrate W to be processed with process liquid. The chuck member 90 includes a body part A1, and a coat layer A2. The body part A1 is composed of a composite material containing carbon fibers 82 and synthetic resin 80. The coat layer A2 covers at least a part of the surface part A100 of the body part A1. The carbon fibers 82 contain multiple fibre elements CF. The surface part A100 of the body part A1 has a surface 80a where the synthetic resin 80 is exposed, and multiple protrusions 20 where some of the multiple fibre elements CF are projected. The coat layer A2 is covering the surface 20b of at least some of the multiple protrusions 20.SELECTED DRAWING: Figure 4 【課題】耐久性を向上しつつ導電性を確保できるチャック部材を提供する。【解決手段】チャック部材90は、処理液によって処理される基板Wを保持する。チャック部材90は、本体部A1と、コート層A2とを含む。本体部A1は、炭素繊維82と合成樹脂80とを含む複合材料によって構成される。コート層A2は、本体部A1の表面部A100の少なくとも一部を覆う。炭素繊維82は、複数の繊維要素CFを含む。本体部A1の表面部A100は、合成樹脂80が露出した表面80aと、複数の繊維要素CFのうちの一部の繊維要素CFが突出した複数の突出部20とを有する。コート層A2は、複数の突出部20のうちの少なくとも一部の突出部20の表面20bを覆っている。【選択図】図4
