Patent ID: 7854893

Claim:
An analysis device in which a sample solution to be analyzed is stored and the sample solution can be transferred, said device comprising: a separation chamber for separating the sample solution into a solution component and a solid component by using a centrifugal force that is generated by rotation of the analysis device; a holding channel to which a part of the solid component separated in the separation chamber is transferred and stored; and an overflow channel which is disposed between the holding channel and the separation chamber, and connected to a joint channel for transferring the sample solution stored in the separation chamber; wherein, after the solution component that is separated in the separation chamber and exists in the joint channel flows into the overflow channel with priority, the solid component separated in the separation chamber is filled in the overflow channel via the joint channel, and thereafter, the solid component in the separation chamber flows into the holding channel from the joint channel via the overflow channel, whereby a part of the solid component is held in the holding channel.
