PURPOSE: To provide an electronic component mounting machine which can make a mounting machine compact.

CONSTITUTION: An electronic component mounting machine is provided with the following: a table 1 for board movement; a camera 3 for board position inspection; a component mounting means 2 which mounts an electronic component on a circuit board on the table; and a camera 4 for mounting state inspection. In the electronic component mounting machine, a movement mechanism 5 which is provided with a slider 5e capable of being moved to a direction perpendicular to the movement direction of the circuit board is arranged, and the camera 3 for board position inspection and the camera 4 for mounting state inspection are attached to the slider 5e. As a result, their arrangement space can be reduced as compared with a case where the respective cameras are dispersed and arranged in the movement direction of the circuit board.
