THERMISTOR

Provided is a thermistor in which a composite containing a plurality of particles including a metal oxide is used as a thermistor layer, and high bonding strength is obtained between the thermistor layer and an electrode. Disclosed is a thermistor including a structure including a thermistor layer and two electrodes and disposed on a base layer, wherein the base layer contains a resin component, the thermistor layer is a composite which includes a plurality of particles including a metal oxide containing at least one first metal element, and an amorphous phase that exists between the plurality of particles and contains the same metal element as the first metal element, the first metal element contains at least one of Mn and Ni, the two electrodes include at least one second metal element selected from the group consisting of Cu, Al, Ag, and Ni, and a bonding layer in which the second metal element and the resin component are diffused into the composite exists between the two electrodes and the thermistor layer.
