To improve image quality of image recording by a recording head using an element substrate by reducing a size of the element substrate having a dummy heater and reducing a distance between recording elements on an end part of the element substrate.SOLUTION: An element substrate having a multilayer structure includes a plurality of recording elements, and a first circuit for inputting a data signal and a clock signal used for driving the plurality of recording elements. A recording element array formed by arraying the plurality of recording elements in a row is arranged by inclining to a side for structuring an outer shape of the element substrate. The recording element on an end part of the recording element array is a dummy element which does not contribute to recording. The first circuit is in a position same as the position in which the dummy element is arranged, and on a layer different from the layer with the dummy element arranged.SELECTED DRAWING: Figure 4 【課題】ダミーヒータを有する素子基板のサイズを低減し、素子基板の端部の記録素子同士の距離を近くすることで、その素子基板を用いた記録ヘッドによる画像記録の高画質化を図る。【解決手段】多層構造の素子基板は、複数の記録素子と、複数の記録素子を駆動するために用いられるデータ信号とクロック信号とを入力する第１の回路を有する。そして、複数の記録素子が一列に配列されて形成される記録素子列が前記素子基板の外形を構成する辺に対して傾いて配置される。また、記録素子列の端部にある記録素子は記録に寄与しないダミーの素子であり、第１の回路はダミーの素子が設けられるのと同じ位置であって、ダミーの素子が設けられる層とは異なる層に設けられる。【選択図】図４
