PROBLEM TO BE SOLVED: To provide a sample analysis chip capable of preventing affection of a reagent to an external environment, and performing plural kinds of treatment.SOLUTION: A sample analysis chip 1 comprises: a main flow channel 24 which is formed into a spiral state on a base material, disposed around an initial reaction part, and whose one end part is communicated with the initial reaction part; plural sawtooth-state storage parts 25 disposed in an inner face 14a of the base material in a radial direction outside on the main flow channel; and plural main storage parts 26 disposed on an opposite side of the main flow channel, on the sawtooth state storage part. The respective sawtooth-state storage part is a space regulated between a first inner face 17 and a second inner face 18 whose one ends 17a, 18a are communicated with the inner face of the main flow channel, and the first inner face is disposed on an upstream side D1 of the second inner face. When a reference line L2 coupling one ends of the first inner face and the second inner face is regulated, a downstream side angle α2 formed of the reference line and second inner face on the sawtooth-state storage part side, is larger than an upstream side angle α1 formed of the reference line and first inner face on the sawtooth-state storage part side. |
