PROBLEM TO BE SOLVED: To provide a semiconductor element mounting device, where a hermetically closed space is formed inside the mounting device including a work transfer passage, and various operations can be carried out, without deteriorating the antioxidant atmosphere by feeding a gas containing nitrogen to the hermetically closed space. SOLUTION: Various processes of applying a wire solder on the works 3, mounting semiconductor elements on the works 3 and unloading the works 3 from the transfer passage to house are carried out, while works 3 fed onto a transfer passage 6 by a feed station 1 are fed successively and intermittently pitch by pitch by a transfer unit 2. Furthermore, a hermetically closed space 4 is formed in a device main body 1A, a shutter 13 is moved by a cylinder 12 to open an opening 11, only when the processes of applying a wire solder on the works 3, mounting semiconductor elements on the works 3, and unloading the works 3 from the transfer passage to house are carried out, so that various processes can be carried out without deteriorating the antioxidant atmosphere.
