PURPOSE:To make uniform the recorded density, by a construction wherein an individual conductor having a bonding terminal end face effectively shortened to the side of a central part of an IC is provided with a conductor resistance correcting region longer than that of an adjacent individual conductor having an effectively longer bonding terminal. CONSTITUTION:In the conductor resistance correcting regions (n) of the individual conductors L1-Lm connected respectively to heating resistors R1-Rm, the length of the ragions (n) is not sequentially monotonously decreased in the direction from the bonding terminal T1 or Tm toward the bonding terminal Tp or Tg, but is locally increased in some areas, and the lengths of the bonding terminals T1-Tm connected to the individual conductors L1-Lm corresponding to the areas are gradually or monotonously reduced to the side of the center of the IC. Accordingly, resistances of the conductors L1-Lm can be made uniform, whereby the density of images recorded by the thermal head can be made uniform, and the size of the head can be reduced. |
