An electromagnetically driven valve includes a valve-opening side moving element and a valve-closing side moving element having rotatably supported support portions and carrying out oscillating movement between a valve-opening position and a valve-closing position around the support portions respectively, and an electromagnet having a coil implemented by a monocoil and arranged between the valve-opening side moving element and the valve-closing side moving element. The valve-opening side moving element and the valve-closing side moving element are held at a position intermediate between the valve-opening position and the valve-closing position while electromagnetic force is not applied. Magnetic permeability of a material forming the valve-opening side moving element is different from that of a material forming the valve-closing side moving element. According to such a structure, an electromagnetically driven valve with a simplified structure, of which initial drive is facilitated, is provided.
