The present invention relates to a biosensor, and more specifically relates to a biosensor in which the production reproducibility is enhanced by limiting the size, in the width direction, of a micro-channel for separating blood cells. In order to achieve the above aim, the present invention provides a biosensor which incorporates a main body and an upper plate joined to the upper edge of the main body, and which comprises: an introducing means for introducing blood formed on the upper surface of the main body; a channel which is formed on the upper surface of the main body and of which one side connects through to the introducing means; and a discharge means which is formed on the upper surface of the main body, connects through to the other side of the channel, and discharges air inside the channel to the outside for the purpose of blood movement; wherein the channel has a minimum width in one section, the minimum width is no less than 0.5 µm and no more than 1 µm, and the height of the channel is 10 times the minimum width. |
