A liquid injection apparatus (1) includes: a first measuring unit (10a) including a first measuring space (13a) inside a first cylinder (11a) and a first piston (12a) moving in the first measuring space (13a); a second measuring unit (10b) including a second measuring space (13b) inside a second cylinder (11b) and a second piston (12b) moving in a second measuring space (13b); a first dispenser (20a) that injects a liquid (19) into a first vessel (90a); a second dispenser (20b) that injects the liquid into a second vessel (90b); a driving mechanism (30) that operates the first piston and the second piston in synchronization; and a first stroke conversion mechanism (60a) which is disposed between the first piston and the driving mechanism, and independently converts a first stroke of the driving mechanism and transmits the converted first stroke to the first piston to control an amount of movement of the first piston independently of an amount of movement of the second piston.
