A method for producing a supporting glove, the method comprising: a first polymer mixed liquid application step of applying a first polymer mixed liquid comprising a first liquid and a first polymer to at least a part of a knitted glove formed by knitting a yarn having a fineness of 33 dtex or more and 180 dtex or less; a first drying step of drying the knitted glove after the first polymer mixed liquid application step; a coagulant solution application step of applying a coagulant solution to the knitted glove after the first drying step; a second polymer mixed liquid application step of applying a second polymer mixed liquid comprising a second liquid and a second polymer, the second polymer mixed liquid comprising 20 mass % or more and 65 mass % or less of the second polymer, to at least a part of an area of the knitted glove after the coagulant solution application step, the area having the first polymer mixed liquid applied thereto; and a second drying step of drying the knitted glove after the second polymer mixed liquid application step, wherein the coagulant solution application step, the second polymer mixed liquid application step, and the second drying step are carried out to form a second polymer film (10B2) so as to form at least a part of an outer surface of the knitted glove in a state of being worn, and carried out to form the second polymer film (10B2) so as to continuously cover the first polymer film (10B1) from the outer surface toward but not reaching an inner surface of the knitted glove in the state of being worn., the method characterized in that: the first polymer mixed liquid comprising 0.2 mass % or more and 4.0 mass % or less of the first polymer, and the first polymer mixed liquid application step and the first drying step are carried out to form a first polymer film (10B1) so as to cover the yarn knitted into the knitted glove over the entire thickness direction of at least the part of the knitted glove. a first polymer mixed liquid application step of applying a first polymer mixed liquid comprising a first liquid and a first polymer to at least a part of a knitted glove formed by knitting a yarn having a fineness of 33 dtex or more and 180 dtex or less; a first drying step of drying the knitted glove after the first polymer mixed liquid application step; a coagulant solution application step of applying a coagulant solution to the knitted glove after the first drying step; a second polymer mixed liquid application step of applying a second polymer mixed liquid comprising a second liquid and a second polymer, the second polymer mixed liquid comprising 20 mass % or more and 65 mass % or less of the second polymer, to at least a part of an area of the knitted glove after the coagulant solution application step, the area having the first polymer mixed liquid applied thereto; and a second drying step of drying the knitted glove after the second polymer mixed liquid application step, wherein the coagulant solution application step, the second polymer mixed liquid application step, and the second drying step are carried out to form a second polymer film (10B2) so as to form at least a part of an outer surface of the knitted glove in a state of being worn, and carried out to form the second polymer film (10B2) so as to continuously cover the first polymer film (10B1) from the outer surface toward but not reaching an inner surface of the knitted glove in the state of being worn., the method characterized in that: the first polymer mixed liquid comprising 0.2 mass % or more and 4.0 mass % or less of the first polymer, and the first polymer mixed liquid application step and the first drying step are carried out to form a first polymer film (10B1) so as to cover the yarn knitted into the knitted glove over the entire thickness direction of at least the part of the knitted glove. the first polymer mixed liquid comprising 0.2 mass % or more and 4.0 mass % or less of the first polymer, and the first polymer mixed liquid application step and the first drying step are carried out to form a first polymer film (10B1) so as to cover the yarn knitted into the knitted glove over the entire thickness direction of at least the part of the knitted glove.
