Summary:To provide a metal-based printed wiring board capable of maintaining the conduction reliability of a wiring pattern located in a bent portion when the metal-based printed wiring board is bent, and a manufacturing method for easily obtaining a metal-based printed wiring board of a bent shape excellent in the conduction reliability of such a wiring pattern.SOLUTION: In a metal-based printed wiring board in which a wiring pattern is formed on one side of a metal plate via a flexible insulating layer, at least one through hole which intersects the wiring pattern in the bent portion is formed in the metal plate in the bent portion of the metal-based printed wiring board.SELECTED DRAWING: Figure 1 【課題】金属ベースプリント配線板を折り曲げた際にその折り曲げ部に位置する配線パターンの導通信頼性を維持できる金属ベースプリント配線板と、このような配線パターンの導通信頼性に優れた折り曲げ形状の金属ベースプリント配線板が容易に得られる製造方法の提供。【解決手段】金属板の一方の面に、可撓性絶縁層を介して配線パターンが形成されている金属ベースプリント配線板であって、当該金属ベースプリント配線板の折り曲げ部における金属板部に、当該折り曲げ部において配線パターンと交差する貫通穴が１つ以上形設されていることを特徴とする金属ベースプリント配線板。【選択図】図１
