PURPOSE:To obtain high-quality pictures by high-density printing of a recording head by making the width of the adjoining portion of the heat generation part of electrodes where an electricity-heat converter is folded in the recording head shallower than that of the heat generation part. CONSTITUTION:Since, in the neighborhood of a heat generation part, there are a lower layer 201, the heat generation part 202, and electrodes 203 and 204, the width W2 of the electrode 203 is shallower than that W1 of the heat generation part 202, the density of the neighborhood can be made higher by as much as W1-W2 per one pitch. In this case, since the width of folded electrode should be set up to an extent not to deteriorate durability when using repeatedly because of no electrode breakage.
