A fluid delivery device according to the present invention has a fluid delivery device body and an electrochemical cell portion for generating a gas when supplied with a DC current. The fluid delivery device body has a partition member transformable by the pressure of a gas, and a gas introduction portion. A first compartment and a second compartment are formed in the fluid delivery device body by the partition member, and a gas generated in the electrochemical cell portion is introduced into the second compartment through the gas introduction portion. A transformable fluid reservoir having a fluid delivery portion is disposed in the first compartment. If the gas generated in the electrochemical cell portion is introduced into the second compartment, the inner pressure of the second compartment increases, and the partition member is pushed, so that a fluid in the fluid reservoir disposed in the first compartment is delivered from the fluid delivery portion.
