To provide a component suction nozzle, a component packaging device, and a component packaging method whereby the component suction nozzle of a turn-over device can be automatically switched with a simple mechanism, the accuracy of packaging components on a board is improved, and inspection and maintenance are performed with great ease.

A component suction nozzle 32A is constituted of a base 3212 having a duct 3214 which is formed therein and is connected to a vacuum source, and a spindle 3251 of a predetermined length in which ducts 3252 and 3253 are formed. A connecting part 3222 is rotatively attached to a connecting part 3213 of the base, and large and small suction ports 3224 and 3225 connected to the ducts 3252 and 3253 are formed at different angle positions on the front end.
