Zusammenfassung:	A non-contact high frequency induction molten resin injection apparatus of multi-point gate type is provided to cope with changes in amount and position of injected resin according to the shape and structure of product. A non-contact high frequency induction molten resin injection apparatus of multi-point gate type comprises an inlet block(50) which is mounted on one end of a molten resin injection machine(30) in order to inject molten resin; a blow nozzle group(20) consisting of blow nozzles(20a,20b,20c) having different length and different runner size which are mounted on the lower side of the inlet block in order to inject the molten resin into a mold for injection-molding a product; first direct contact heating units(70a,70b, 70c) for heating up the tip end of each blow nozzle; and induction coil parts(22a,22b,22c) enclosing the back end of each blow nozzle in which Nozzle tips(21a,21b,21c) are formed.
