To provide a chip part supply device capable of ensuring sufficient air suction force and improving the configuration in which the attitude of a chip part is likely to become oblique and allowing a stopper in contact with the most tip of the chip part to move in the direction in which it leaves when the chip part in a tubular feed passage is fed by air suction and a suction pin of a mounted head picks up the chip part at the most tip.

A terminal of a square groove passage 253 is constituted such that the most tip of a fed chip part 15 is blocked by an end face 301 of a stopper 30. The stopper 30 is slidably fitted in a groove 401 of a block guide 40, and when a cam part 532 of a shutter 53 moves to the right and left, the end face 301 comes into contact with or leaves the terminal of the square groove passage 253. The stopper 30 is provided with an air suction hole 307 and a slit 308 and opens the hole for the square groove passage 253 from the end face 301 to suck the chip part 15 by air.
