Abstract: To provide a biochip, a biochip manufacturing method, an electrophoresis method, and an electrophoresis apparatus, by which the detection accuracy may improve, there is a biochip introducing a sample in band form into a sample separation passage, by a means for reducing the band width of sample, at which the sample is before being introduced in the sample separation passage in band form. The band of sample supplied to the sample separation passage is compressed, and the expansion by diffusion may be prevented, thus the detection accuracy may improve.
