To provide a terminal block with a temperature fuse having excellent insertion capability and connection capability of a lead, and capable of preventing a short circuit caused by a foreign substance.

In this terminal block equipped with a temperature fuse, a contact housing part opened backward is formed in a housing of the terminal block to house contacts from the back face; a lead insertion hole is formed in a surface of the housing by boring it; and leads are allowed to be connected from the front side. In this case, it is preferable that a lead guide part is formed on the contact housing part side of the lead insertion hole, and a taper surface is formed on the front side of the lead insertion hole.
