| 摘要 |
A protection element for preventing over- current and over-voltage, comprising a base substrate (1), a pair of electrodes (4, 5) formed on the base substrate (1), and a low-melting- point metal element (2) connected between the pair of electrodes (4, 5) to cut off a current running between the electrodes (4, 5) by being fused. An insulation cover plate (13) is positioned and fixed while being kept in contact with the electrodes (4, 5) as spacer members.
