An electric deviceis an organic positive thermistor in which, between two plate electrodesandconstituting an electrode couple, a conductive memberis disposed in a state being in a close contact with the plate electrodesand. The conductive memberis formed of many piled up resin particles each having its surface formed with a conductive layer of a residual material (fullerene residual), which is the soot including fullerenes generated via, for example, an arc discharging method, from which at least a part of fullerenes is removed. Such conductive layers are joined to each other to structure the conductive path and the conduction of the electric deviceis ensured in a normal state. When an inrush current flows, the conductive path is readily shut off by a small inflation of the resin particles due to the temperature rise.

Conductive member and manufacturing method thereof, and electric device and manufacturing method thereof

A thermistor is provided with a pair of opposed electrodes, and a thermistor body layer disposed between the pair of electrodes and including a cured body of a curable resin composition containing a thermosetting resin and conductive particles, and an average particle diameter of secondary particles of the conductive particles is in a range of 3.8 to 17.0 &#x3bc;m.

Thermistor

An organic positive temperature coefficient thermistor device comprising a pair of electrodes disposed so as to oppose each other, and a thermistor body having a positive resistance-temperature characteristic disposed between the electrodes, wherein the thermistor body is constituted by a cured product of a mixture containing an epoxy resin including a flexible epoxy resin, a curing agent, and an electrically conductive particle.

Organic positive temperature coefficient thermistor device

There is provided a process for producing an organic PTC thermistor including the steps of: At least one of the mixing step, the layer-forming step and the laminating step is conducted under reduced pressure. An organic PTC thermistor obtained by the production process is also provided.

Organic PTC thermistor and production

This invention relates to a thermistor comprising a pair of opposite electrodes and a thermistor body positioned between the pair of electrodes, wherein the thermistor body consists of a cured product of the resin composition comprising an epoxy resin including a cycloaliphatic epoxy resin, a curing agent and electrically conducting particles.

Resin composition for forming thermistor body, and thermistor
