PROBLEM TO BE SOLVED: To provide an electromagnetic fluid automatic opening and closing device incorporated in a pipe or a housing supplying gas or fluid, to automatically cut off the fluid in accordance with external electric signals, miniaturizable, easily manufacturable and reducing the manufacturing cost, being disposed on a channel directly in opposition thereto. SOLUTION: This electromagnetic fluid automatic opening and closing device includes a frame part coaxially incorporated in the pipe or the housing configurating the fluid channel, a penetration part having one or more holes to form the channel on the frame part, one or more coil parts disposed inside the frame part to generate the electromagnetic force, a rotor having the magnetic force and faced to the frame part to open and close the channel by the interaction with the electromagnetic force generated from the coil parts, a shaft for supporting the rotor, and a case supporting the frame part and configurating the outer shape.
