An analyzing device has one end of a supplying capillary channel opened at a spot application section formed so as to protrude from an analyzing device main body. The supplying capillary channel is connected to a microchannel structure formed inside the analyzing device main body. A sample liquid is applied to the spot application section and is suctioned by a capillary force of the supplying capillary channel. The analyzing device is used for reading in which a suctioned solution is accessed. The analyzing device includes a leading end of the spot application section that has an inclined face. The end of the supplying capillary channel is opened on the inclined face.

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.

A feature of an analyzing device is that a peeling portion () extending outward is partially connected to the outer edge of a reagent retaining portion () that is formed in a separating chamber () provided in a main unit case () and retains a reagent (). With this configuration, when a droplet of the reagent () is dried and fixed on the reagent retaining portion (), an external force applied to the droplet can be smaller than that on other portions. The dried reagent () starts shrinking from the position of the peeling portion. At the completion of drying, the reagent () can be smaller in size than the reagent retaining portion () in plan view and can be larger in thickness than the related art.

In a read label as an information recording medium and a method for recording information thereon according to the present invention, the read label includes: an adhesive layer; a metal film layerdisposed on the surface of the adhesive layer; and a light-transmissive protective film layerdisposed on the surface of the metal film layer. The adhesive layerand the light-transmissive protective film layerare larger in thickness than the metal film layer, and an evaporated and removed portion is formed in a part of the metal film layerby radiating a laser beam from the side of the light-transmissive protective film layer

An inlet () of a capillary tube channel that feeds a liquid from a mixing cavity () to measurement spots is formed near one () of the wall surfaces of the upper and lower surfaces of the mixing cavity () situated in a direction of oscillation for mixing. On the other wall surface (), a level difference () is formed such that an inner gap is larger than an outer gap in the mixing cavity (), so that a solution is reliably fed from the mixing cavity to the measurement cells.
