PURPOSE:To obtain a electromagnetic relay with high voltage withstanding by coating a permanent magnet at the upper end portion thereof and a magnetic pole at the lower portion rather than the upper end portion thereof with resin agent which is charged into a box base and solidified. CONSTITUTION:In an electromagnet block 2, at least a permanent magnet 28 at the upper end portion thereof and magnetic poles 21a and 21b at the lower portion rather than the upper end portion thereof are coated with resin agent which is charged into a box base 1 and solidified. Thus, the coil of the electromagnet block 2 is isolated from the movable contact of an armature block. Therefore, insulation of the coil and the movable contact is improved, so that voltage withstanding is also improved. |
