Abstract
A fluid ejection device ejecting a fluid, the fluid ejection device includes: a fluid ejection unit; a fluid container; a delivery needle; and a guard cover. The fluid ejection unit ejects a fluid onto an ejection target. The fluid container includes a container portion and a withdrawal portion. The container portion contains a fluid for ejection, and the withdrawal portion allows withdrawal of the fluid contained in the container portion. The delivery needle sticks through the withdrawal portion to provide a flow passage which communicates with the fluid ejection unit. The guard cover projects over the delivery needle to prevent the withdrawal portion from approaching the delivery needle from a direction intersecting a center axis of the delivery needle.
