PROBLEM TO BE SOLVED: To prevent a magnet incorporated into an electric resistance welding electrode from displacing relative to a container in the container.SOLUTION: A magnet unit holds a magnetic material product 19 inserted into an electric resistance welding electrode 100. In the magnetic unit, a magnet 25 in a container 24 is sealed by a lid member 26 fixed to a container opening part. Cushioning members 37 are disposed in one of or both of a space between the magnet 25 and a container inner surface and a space between the magnet 25 and an inner surface of the lid member 26. The cushioning members 37 prevent the magnet 25 from displacing relative to the container 24. |
