A separation chip for separating an insoluble component from a suspension using centrifugal force by rotation, includes a suspension holding tank, a separation liquid holding tank, and an insoluble component holding tank which are arranged in this order from an inner circumferential side during rotation. In the separation chip, the suspension holding tank and the insoluble component holding tank are connected with each other, the insoluble component holding tank and the separation liquid holding tank are connected with each other by a narrow portion, and in the insoluble component holding tank, a connecting portion with the suspension holding tank is positioned further toward an outer circumferential side than the narrow portion. |
