Abstract

An analyzing device has a main body and is configured to draw a sample liquid from a spot application section of the main body and transfer the sample liquid to a measurement chamber via a microchannel structure formed inside the main body by a centrifugal force. The spot application section has an inlet. The analyzing device includes a supplying capillary channel formed within the spot application section. The supplying capillary channel has an end connected to the inlet of the spot application section. The analyzing device also includes a holding chamber connected to another end of the supplying capillary channel and having a thickness sized to generate a capillary force to move the sample liquid. The holding chamber is formed between a first side wall and a second side wall. The first side wall and the second side wall define the holding chamber.
