Abstract
There is provided a flow channel member in which a flow channel of a liquid is formed by a plurality of flow channel forming members, the flow channel member including: a first flow channel forming member that includes a light absorbing member having absorbing properties with respect to laser light; a second flow channel forming member that includes a light transmitting member having transmitting properties with respect to the laser light and is welded to a first surface of the first flow channel forming member; and a third flow channel forming member that includes a light transmitting member having transmitting properties with respect to the laser light and is welded to a second surface of the first flow channel forming member. The first surface and the second surface are provided at positions where planes along the both surfaces intersect with each other.
