Claim Text:
1. A flow path structure, comprising therein a plurality of flow paths into which a fluid may be introduced, wherein: said plurality of flow paths includes flow paths each having a fluid inlet and a different flow path length, each of said flow paths comprising a small diameter part and a large diameter part, wherein the small diameter part is closer to the fluid inlet than is the large diameter part, wherein said flow paths are arranged in parallel and each of said flow paths has a bend at the small diameter part, all of the bends being in the same direction relative to the direction of the length of the large diameter part of the flow paths, to define an inner side of the bends of the flow paths, which inner side is provided more toward said same direction than is an outer side of the bends of the flow paths, whereby the length of the flow paths located relatively closer to an outer side of the bends is greater than the length of the flow paths located relatively closer to an inner side of the bends, to define a first straight section of the small diameter part between the fluid inlet of the respective flow path and the bends, and a second straight section of the small diameter part between the bends and a fluid outlet of the respective flow path, and wherein the length of the second straight section of the small diameter part of at least one of the flow paths located relatively closer to an inner side of the bends is greater than the length of the second straight section of at least another one of the flow paths located relatively closer to an outer side of the bends.
