Abstract
A fluid path structure is manufactured by way of an aligning step of aligning a first resin part with a second resin part by inserting a projection formed on the first resin part into a corresponding hole formed in the second resin part and a welding step of welding joint surfaces of the first resin part and the second resin part, thereby forming a fluid path. The aligning step is executed so as to narrow the gap between the projection and the hole to a minimum at a base side of the projection relative to a half of the height of the hole and the welding step is executed only at the base side of the projection relative to the half of the height of the hole so as to make the lateral surface of the projection only partially contact with the lateral surface of the hole.

A method of manufacturing a fluid path structure comprising:
- an aligning step of aligning a first resin part with a second resin part by inserting a projection formed on the first resin part into a corresponding hole formed in the second resin part;
- and
- a welding step of welding joint surfaces of the first resin part and the second resin part that have been aligned, thereby forming a fluid path;
- the aligning step being executed so as to narrow the gap between the projection and the hole to a minimum at a base side of the projection relative to a half of the height of the hole;
- the welding step being executed only at the base side of the projection relative to the half of the height of the hole so as to make the lateral surface of the projection only partially contact with the lateral surface of the hole.
A fluid path structure produced by inserting a projection formed on a first resin part into a hole formed in a second resin part so as to form a fluid path along the joint surfaces of the first resin part and that of the second resin part;
- the gap between the projection and the hole is narrowed and minimized at a base side of the projection relative to a half of the height of the hole.
