Claim:
1. A heater module for a heater of a fluid infusion apparatus, comprising: a laminated structure of an insulation substrate; a resistance pattern laminated on one side of the insulation substrate with a pure metal or an alloy which is a mixture of two or more metals at a predetermined ratio and having a resistance value which is set by a pattern having a length and a cross-sectional area; and a first insulator layer coated on an upper surface of the resistance pattern by a predetermined method to protect and insulate the resistance pattern; and a conductor layer in which a metal material is deposited on the upper surface of the first insulator layer by a predetermined method; and a thin film protective layer deposited on the upper surface of the conductor layer to provide insulation from the conductor layer, waterproofing, corrosion resistance, and chemical resistance, wherein a part of a ground formed in the resistance pattern by masking in the coating of the first insulator layer is exposed, and the conductor layer deposited on the upper surface of the first insulator layer electrically contacts the part of the ground which is exposed.
