Claim:
1. A microchip comprising: a substrate structure including a first substrate layer, a second substrate layer, and a third substrate layer, wherein the second and third substrate layers are provided in direct contact with opposite sides of the first substrate layer, and wherein each of the second and third substrate layers is a gas-impermeable substrate layer; and a fluid channel disposed between the first substrate layer and the second substrate layer, wherein the fluid channel includes at least one injection site, at least one fluid well, and at least one fluid flow passage provided in the first substrate layer, wherein the third substrate layer has a hole for injecting a sample solution, and wherein the at least one injection site is configured to be injected with the sample solution by injection through the hole and the first substrate layer, and wherein the fluid channel has a pressure lower than atmospheric pressure.
