1. A method of welding a first member and a second member together, the method comprising:
performing a preparation process of preparing the first member and the second member;
performing a contact process of bringing the first member and the second member into contact so as to form a space between the first member and the second member;
performing a welding-horn contact process of bringing a welding horn into contact with the first member or the second member to form a fluid passage that includes a groove portion;
performing a vibration process of vibrating the welding horn to weld the first member and the second member together by frictional heat; and
performing a fluid-flow process in which the space channels a fluid through the space to flow through the space, through the fluid passage to outside of the contacted first and second members,
wherein the fluid-flow process is performed during the vibration process, and
wherein, in the welding-horn contact process, the welding horn is brought into contact with the first member,
wherein the first member has a first through hole penetrating the first member,
wherein the second member has a second through hole penetrating the second member,
wherein the space communicates with the first through hole and the second through hole, and
wherein the fluid used in the fluid-flow process is made to flow into the space from the second through hole.
