PCT No. PCT/JP94/02063 Sec. 371 Date Nov. 1, 1995 Sec. 102(e) Date Nov. 1, 1995 PCT Filed Dec. 8, 1994 PCT Pub. No. WO95/17760 PCT Pub. Date Jun. 29, 1995A slim-type small size electromagnetic relay is made using semiconductor manufacturing techniques to form a silicon substrate 2 having a planar movable plate 5 and a torsion bar 6 for axially supporting the movable plate 5 formed integrally therewith, with a planar coil 7 provided on an upper face of the movable plate 5 and a movable contact 9 provided on a lower face. Glass substrates 3, 4 are provided on upper and lower faces of the silicon substrate 2, with fixed contact 11 contactable with the movable contact 9 provided on the lower glass substrate 4. Permanent magnets 13A, 13B and 14A, 14B for producing a magnetic field at the planar coil 7 are fixed to the glass substrates 3, 4. Rotation of the movable plate 5 against the torsion force of the torsion bar 6 is controlled by passing a current through the planar coil 7 to produce a magnetic force, thereby causing contact or separation of the movable contact 9 and the fixed contact 11.
