PROBLEM TO BE SOLVED: To provide a head base body which can ease stress concentration in a glaze layer below an electrode line, and to provide a manufacturing method thereof, a recording head, and a recording apparatus. SOLUTION: The head base body includes a head substrate 11, the glaze layer 12 formed on the entire surface of the top surface of the head substrate 11, a plurality of heating elements and a plurality of electrode lines 14 formed on the glaze layer 12, and electrode pads 17 comprised of a nickel plating layer formed on the top surface of the plurality of electrode lines 14. The peripheral end surface of the electrode pad 17 is formed away from the peripheral end surface of the electrode line 14. COPYRIGHT: (C)2011,JPO&INPIT
