PROBLEM TO BE SOLVED: To provide a microchip with which a sample solution can be introduced to the inside of a well or a channel in a short time and easily without generating bubbles.SOLUTION: A microchip is provided in which an introduction part and a deaeration area are provided independently. The inside of the introduction part is made into negative pressure with respect to atmospheric pressure and a liquid is injected into the introduction part by puncturing. The inside of the deaeration area is made into negative pressure with respect to the atmospheric pressure and the deaeration area is provided for deairing the inside of a cavity of a needle by being punctured with the needle for injecting the liquid into the introduction part by puncturing. In the microchip, by puncturing the deaeration area with the needle and then puncturing the introduction part, the liquid can be injected into the introduction part while removing air inside the cavity of the needle. |
