The invention provides a flow path member, a liquid ejecting head, and a liquid ejecting device which inhibit generation of bubbles in an ink path and has great ejection performance. The flow path member includes a first flow path plate (77) formed with a first ink flow path (81) that communicates between the ink storage tank and the first head chip. The first ink flow path (81) includes a narrowwidth flow path (91) on the upstream side, a filtration flow path (84) on the downstream side with respect to the narrow width flow path (91), and a connection flow path (92), which connects the narrow width flow path (91) and the filter flow path (84). In the connection flow path (92), the flow path width gradually increases from the upstream side to the downstream side. In another aspect, the flow path depth is gradually reduced from the upstream side to the downstream side. 本发明提供抑制在墨水流路内的气泡的产生、并且吐出性能优秀的流路部件、液体喷射头以及液体喷射装置。具备形成有使墨水储罐和第头芯片之间连通的第墨水流路(81)的第流路板(77)，第墨水流路(81)具备：窄宽度流路(91)，其位于上游侧；过滤流路(84)，其相对于窄宽度流路(91)位于下游侧
