Testing microchip and testing apparatus using the same

A testing microchip, comprising:

• a specimen storage section that stores a specimen;
• a reagent storage section that stores a reagent;
• a reaction section having a reaction flow channel for mixing the specimen stored in the specimen storage section and the reagent stored in the reagent storage section and performing a predetermined reaction processing;
• a testing section having a testing flow channel for performing a predetermined test of a reaction product obtained from the reaction in the reaction section;
• a liquid feed control section;
• and
• a gas bubble trapping structure,
• wherein,
• the specimen storage section, the reagent storage section, the reaction section, and the testing section are connected continuously by a series of flow channels from an upstream side to a downstream side;
• the liquid feed control section is provided for the series of the flow channels, stops passing liquid until a liquid feeding pressure in a normal direction from the upstream side to the downstream side reaches a predetermined pressure, and passes the liquid when the liquid feeding pressure becomes higher than the predetermined pressure;
• and
• the gas bubble trapping structure is provided at the liquid feed control section and traps a gas bubble in the liquid that flows in the flow channel so that the gas bubble does not flow to the downstream side and only the liquid passes to the downstream side.
