Electromagnetic relay

An electromagnetic relay, comprising:

• a base block;
• an electromagnet unit supported on a first face of the base block, the electromagnetic unit including an iron core, a coil winded around the iron core, and an armature configured to be pivotably supported on the iron core;
• and
• a contact unit supported beneath a second face of the base block, the second face being opposite the first face on which the electromagnet unit is supported, the contact unit including a movable contact spring with a movable contact provided thereon and a fixed contact spring with a fixed contact provided thereon,
• wherein the base block includes:
• a first insulating wall extending from the first face alongside the electromagnetic unit, the first insulating wall covering the coil and a side of the iron core;
• a second insulating wall extending from the second face alongside the contact unit, the second insulating wall provided on an opposite side from the first insulating wall across the second face;
• and
• a third insulating wall having the first face and the second face and situated between the coil and the contact unit, the third insulating wall joining the first insulating wall and the second insulating wall.
