摘要： A protective element has a heat-generating member and a low-melting metal member on a substrate, in which the low-melting metal member is blown out by the heat generated by the heat-generating member, wherein at least two strips of low-melting metal member are provided as the low-melting metal member, for example, between the pair of electrodes that pass current to the low-melting metal member, so that the lateral cross section of at least part of the low-melting metal member is substantially divided into at least two independent cross sections. This protective element has a shorter and more consistent operating time. It is preferable here to provide at least two strips of low-melting metal member between the pair of electrodes that pass current to the low-melting metal member. It is also preferable to provide one strip of low-melting metal member having a slit in its center, between the pair of electrodes that pass current to the low-melting metal member.

摘要： A protection circuit is provided. The protection circuit protects a battery pack from overcurrents and overvoltages using sensing means and a protection device having a heating resistor and a fuse element provided on a circuit board. This protection circuit allows for sharing a protection device regardless of the current rating and the voltage rating of the battery pack, thereby being manufactured at low costs. A protection circuit protects a battery pack having serially connected rechargeable batteries from overcurrents and overvoltages. The protection circuit includes a protection device having heating resistors and fuse elements provided on a circuit board, and sensing means for detecting an overvoltage across any of the batteries in the battery pack and switching a current flowing into the heating resistor. The protection circuit allows the sensing means in an overvoltage condition to switch on the current flowing through the heating resistor. This allows the voltage across a predetermined number of the serially connected batteries in the battery pack to be applied to the heating resistor, thereby causing the heating resistor to generate heat and the fuse element to be melted.

摘要： A protective element contains a heat-generating member and a low melting metal member on a substrate. The low melting metal member is caused to blow out by the heat generated by the heat-generating member. The number of locations on the low melting metal member which are able to blow out is larger than the number of locations which are supposed to blow out so that the protective element is endowed with a “fail-safe” function.

摘要： A protective element with improved spherical segmentation performance during the melting of a low-melting metal member, has a heat-generating member and a low-melting metal member on a substrate, in which the low-melting metal member is heated and blown out by the heat generated by the heat-generating member. There is a region in which the low-melting metal member is suspended over the underlying base (such as an insulating layer), and when S (μm2) is the surface area of a lateral cross section of the low-melting metal member 4 between a pair of low-melting metal member electrodes 3a and 3b or 3b and 3c sandwiching the region, and H (μm) is the height at which the suspended region is suspended, then the relationship H/S≧5×10−5 is satisfied. It is preferable here that the upper surfaces of both of the pair of low-melting metal member electrodes protrude beyond the upper surface of the underlying insulating layer.
