To provide a fuse holder capable of eliminating the risk that the power supply of a sound electric circuit goes out even in case one has removed the fuse by mistake during the current being fed.

The fuse holder is composed of the fuse for protecting the circuitry of any electric circuit, a clip conductor for connecting the fuse with the electric circuit, and a connecting terminal for connecting the clip conductor with the external line, wherein a bypass means for bypassing the fuse is formed so that a socket or assisting connecting terminals is/are installed between the clip conductors at the two ends and the connecting terminal, and a shortcircuiting means is provided to shortcircuit the socket or between the assisting terminals.
