Contact device and electromagnetic relay equipped with same

A contact device, comprising:

• an electromagnet device including a coil and an iron core to be magnetized by the coil;
• an armature arranged to face the iron core and arranged to be swingable by a magnetic field generated by the coil;
• a first contact;
• a second contact that is movable relative to the first contact by the armature swings and is brought into contact with or separated from the first contact;
• a first body part including the first contact;
• a second body part including the second contact;
• and
• a yoke fixed to at least one of a surface of the first body part, which is a surface opposite to the surface to face the second body part or a surface of the second body part, which is a surface opposite to the surface to face the first body part, wherein
• at least a part of the yoke is arranged along magnetic flux generated by a current flowing through one body part of the first body part and the second body part that is fixed to the yoke, in a region where the first body part and the second body part overlap each other when viewed along an axis in which the first contact and the second contact move relative to each other while the first contact and the second contact are in contact with each other.
