Summary:To provide a jet hole plate, a liquid jet head, a liquid jet recording device, and a manufacturing method for the jet hole plate which can achieve prolonged lifetime.SOLUTION: A jet hole plate is used in a liquid jet head. The jet hole plate includes a metal substrate having a plurality of jet holes. The metal substrate has a principal surface on which injection ports of the respective jet holes are arranged. Surface roughness (arithmetic average roughness Ra) of an injection port end edge area of each jet holes is smaller than surface roughness (arithmetic average roughness Ra) of a peripheral area around the injection port end edge area on the principal surface.SELECTED DRAWING: Figure 8 【課題】長寿命化が可能な噴射孔プレート、液体噴射ヘッド、液体噴射記録装置、および噴射孔プレートの製造方法を提供する。【解決手段】本開示の一実施の形態に係る噴射孔プレートは、液体噴射ヘッドに用いられる噴射孔プレートである。この噴射孔プレートは、複数の噴射孔が設けられた金属基板を備えている。金属基板は、各噴射孔の噴出口が設けられた主面を有している。その主面において、各噴射孔の噴出口端縁領域の表面粗さ（算術平均粗さＲａ）が、噴出口端縁領域の周囲にある周囲領域の表面粗さ（算術平均粗さＲａ）よりも小さくなっている。【選択図】図８
