Abstract:
A method of producing thermistor chips, said method comprising the steps of:obtaining strips of a mother substrate each elongated in a longitudinal direction, made of a sintered ceramic plate having a specified resistance-temperature characteristic, and having a mutually oppositely facing pair of first and second main surfaces and a pair of first and second side surfaces extending between said first and second main surfaces, said first main surface having formed thereon a plurality of mutually parallel grooves extending perpendicularly to said longitudinal direction;forming a first ohmic electrode which extends continuously from said first main surface to said first side surface and a second ohmic electrode which extends continuously from said second main surface to said second side surface;stacking a plurality of said strips one on top of another by aligning the grooves of said strips and adhesively attaching said strips together with an electrically insulating material to thereby obtain a layered structure;breaking up said layered structure along said aligned grooves to thereby obtain individual units.
