Electromagnetic relay

An electromagnetic relay comprising:

• a pair of fixed contact terminals arranged at predetermined intervals;
• a movable contact terminal that approaches the pair of fixed contact terminals and separates from the pair of fixed contact terminals, thereby making a portion between the pair of fixed contact terminals conducted or cutoff;
• a contact part between the pair of fixed contact terminals and the movable contact;
• a contact terminal housing that accommodates the pair of fixed contact terminals, the movable contact terminal and the contact part, the contact terminal housing including an arc extinguishing chamber formed therein as a space used for extending an arc produced between the fixed contact terminals and the movable contact terminal;
• and
• a magnet disposed in a lateral side of the contact part with respect to a direction where the movable contact terminal extends from one fixed contact terminal to the other fixed contact terminal among the pair of fixed contact terminals, the magnet producing magnetic field causing the arc to be extended in a predetermined direction and guiding the arc to the arc extinguishing chamber, wherein
• a communication hole is provided in the contact terminal housing, formed at a portion positioned in a predetermined direction relative to the contact part, the communication hole causing the arc extinguishing chamber to communicate with outside the arc extinguishing chamber.
