摘要：
A method of manufacturing a flow path member includes inserting the first flow path member into each concave portion of the second flow path member and welding the first flow path member and the second flow path member in a circumferential direction of a region where the first flow path and the second flow path communicates each other; and providing two or more injecting portions which are provided with a gap wider than a gap between a wall surface of the concave portion which faces the first flow path member and a circumference surface of the first flow path member inserted into each concave portion which faces the wall surface, communicate with each concave portion, and are opened to the same side as the concave portion to have a concave shape to each concave portion in the second flow path member.
