Abstract
A recording element board has a plurality of heat-generating resistor elements arranged in a row and each of the plurality of heat-generating resistor elements comprises a heat-generating resistor layer and first and second pairs of electrodes connected to the heat-generating resistor layer. The first and second pairs of electrodes contact the heat-generating resistor layer at the opposite surfaces thereof to each other. The first pair of electrodes is formed as vias, while each surface of the second pair of electrodes is inclined so as to gradually reduce the thickness thereof toward the end thereof.
