PURPOSE: A plate(6) for ink jet head is provided to expand the width of the first generation of heat means in the vertical direction of a movable way(4) and shorten the length the first exothermic means(11,31,51) in the direction of a movable way(4) to safely supply ink, although the head is operated for lots of records by a high frequency and make a movable way and an exothermic materials highly dense. CONSTITUTION: A plate(6) for ink jet head comprises; numbers of delivery ports(3a) supplying liquid; numbers of liquid movable ways being connected to delivery ports; an ink jet head comprising the first and the second exothermic means arranged in series in the direction of a liquid movable way to make heating energy used to deliver liquid from the delivery ports and operated by over 4 kilohertz driving frequency; the first exothermic means(11,31,51) comprising exothermic resistance materials(11a,31a,51a) connected electrically in series and arranged in the vertical direction of a liquid movable way; the second exothermic means(11b,31b,51b) comprising at least one exothermic resistance material, thereby high density of exothermic resistance material and a movable way(4) as well as safe delivery of liquid are provided.
