PURPOSE: To inexpensively provide an energizing head which has high resolution and excellent durability by forming the insulating layer which contains specific amount ratios of hexagonal boron nitride and talc.
CONSTITUTION: In an energizing head formed of a laminate in which electrically conductive layers 406 and electrically insulating layers 407 are alternately laminated in a thicknesswise direction is formed so that the ends of the layer 406 are contacted with a recording sheet to record, the layers 407 are constructed to contain 25W60wt% of a mixture of hexagonal boron nitride and talc so that the boron nitride is 5wt% or more. Thus, the head which has high resolution and long lifetime can be obtained. When the hexagonal crystal boron nitride and talc are contained in epoxy resin, the heat having high mechanical strength can be obtained.
