PROBLEM TO BE SOLVED: To provide an eco-friendly fishing hook having excellent corrosion resistance, good workability, and high safety, and having a low cost.SOLUTION: The fishing hook is produced by using a steel containing 0.1-0.8 mass% of carbon as a matrix, and plating the matrix with an alloy containing 2.0-4.0 mass% of silver based on the amount of tin into a calculated surface thickness of 3-6 &mum. Alternatively, the fishing hook is produced by using a steel containing 0.1-0.8 mass% of carbon as a matrix, and plating the matrix with an alloy containing 0.7-4.0 mass% of copper based on the amount of tin into a surface thickness of 3-6 &mum. The fishing hook is preferably produced by using a flux treatment with a fluxing liquid containing zinc chloride.COPYRIGHT: (C)2011,JPO&INPIT【課題】低コストにて、耐食性に優れ、作業性がよく、安全性の高い環境に優しい釣針の提供を図る。【解決手段】母材を炭素0.1~0.8mass%含んだ鋼とし、スズに対し2.0~4.0mass%銀を含有した合金を計算上3~6ミクロンの厚さ表面にめっきした釣針を提供する。また、母材を炭素0.1~0.8mass%含んだ鋼とし、スズに対し0.7~4.0mass%銅を含有した合金を3~6ミクロンの厚さ表面にめっきした釣針を提供する。これらの釣針を製造するのに際しては、塩化亜鉛を含有するフラックス液にて、フラックス処理することが望ましい。【選択図】なし
