PROBLEM TO BE SOLVED: To provide a board for a recording head which is equipped with an inspection electrode for a cavitation resistant membrane, and is miniaturized, and to provide a recoding head equipped with the board, and a recording apparatus. SOLUTION: For this board 1000 for recording head, each common power source wiring is divided into at least two directions crossing a heat conversion element train. In a region between each divided common power source wiring, connecting wiring 1501 which electrically connects cavitation resistant membranes 1401 with each other, and pulling-out wiring 1502 which electrically connects each cavitation resistant membrane 1401 and an electrode pad 1113 for protective film inspection are installed.
