Microinjection apparatus and method of injecting fluid

A method of injecting a fluid, comprising:

• injecting a first fluid from a tip end of a capillary into an object captured in a solution at a predetermined position;
• causing the tip end of the capillary to retreat after the first fluid has been injected;
• and
• discharging a second fluid from an outlet when the capillary retreats, the second fluid directed toward the tip end of the capillary.

A method of making a minute body, comprising:

• moving a capillary forward toward a minute body for injecting a substance into the minute body, a fluid being discharged from a position adjacent to the capillary toward the minute body;
• stopping discharge of the fluid when the capillary is stuck into the minute body;
• injecting the substance into the minute body;
• and
• moving the capillary backward from the minute body, the fluid being discharged from a position adjacent to the capillary toward the minute body.
