PROBLEM TO BE SOLVED: To provide a double-barreled delivering instrument capable of efficiently discharging the content while preventing any flow-in of air. SOLUTION: The double-barreled delivering instrument comprises a base part 3 for holding two containers 1 and 2 which are filled with content of different kinds and arranged at its mouth part, a pump part 4 which is held by the base part 3 to suck the content in the respective containers 1 and 2 by the operation of a lever L, and pressure-feed the content, and a nozzle part 7 which merges and mixes the content pressure-fed by the pump part 4 and discharges the content to the outside. The base part 3 consists of a connection member 3a which has openings h1 and h2 connected to the inside of the containers 1 and 2, and is fitted to a tip of each mouth part of each container to keep a space between the containers 1 and 2 and the pump part 4 in an airtight manner, and a holder part 3b which surrounds and holds an outside wall of the connection member 3a. A flap having an obliquely upward locking claw which is locked to each lower end of each mouth of the containers 1 and 2 in an elastically displaceable manner to prevent the containers 1 and 2 from being drawn from the connection member 3a is provided on the holder part 3b.
