Abstract
A die having a plurality of cavities and a temperature sensor for acquiring a temperature value in which the number of the cavities is larger than that of electrothermal conversion elements. When viewed from a direction perpendicular to the surface of a parting line, all cavities and a temperature sensor are arranged in a region occupied by the electrothermal conversion elements. Interval between the outlines of the cavities is smaller than the minimum interval between the outline of the cavity and the electrothermal conversion element, and the shortest distance between the electrothermal conversion element and the temperature measuring portion of a temperature measuring element is shorter than the minimum interval between the outline of the cavity and the electrothermal conversion element.
