The stick-type product includes a handle part that is graspable by a user; a brush rod extending from the handle part; and an application part provided at one end of the brush rod and configured to apply a cosmetic article. The application part has portions of different temperatures by being provided with materials which are capable of heat generation and which have different thermal conductivities. ## Claims ### Claim 1 A stick-type product having a heating function comprising: a handle part that is graspable by a user; a brush rod extending from the handle part; and an application part provided at one end of the brush rod and configured to apply a cosmetic article, wherein the application part comprises: a heat-generating applicator part having a plurality of metal brushes formed along an outer circumference thereof; and a brush part including non-metal brushes detachable from the heat-generating applicator part and formed of a material having a lower thermal conductivity than the metal brushes. ### Claim 2 (depends on 1) The stick-type product having a heating function of claim 1, wherein the metal brushes are formed of metal; and the non-metal brushes are formed of nylon having a lower thermal conductivity than the metal. ### Claim 3 (depends on 1) The stick-type product having a heating function of claim 1, wherein each of the metal brushes includes: a flat surface parallel to a direction in which the heat-generating applicator part extends; a first inclined surface extending from one side of the flat surface and inclined in one direction relative to the direction in which the heat-generating applicator part extends; and a second surface extending from the other side of the flat surface and inclined in the other direction relative to the direction in which the heat-generating applicator part extends. ### Claim 4 (depends on 1) The stick-type product having a heating function of claim 1, wherein a metal brush groove is formed between the plurality of metal brushes, which is a space in which the cosmetic article is collected. ### Claim 5 (depends on 1) The stick-type product having a heating function of claim 1, wherein a heat-generating element capable of heating to a predetermined temperature is provided within the heat-generating applicator part. ### Claim 6 (depends on 1) The stick-type product having a heating function of claim 1, wherein the heat-generating applicator part includes: a first heat-generating applicator having a first space formed therein capable of accommodating the brush part; and a second heat-generating applicator integrally formed with the first heat-generating applicator and having a second space in which a heat-generating element capable of being heated to a predetermined temperature is inserted, and wherein the metal brushes are formed along an outer circumference of the first heat-generating applicator and the second heat-generating applicator. ### Claim 7 (depends on 6) The stick-type product having a heating function of claim 6, wherein based on a cross-section of the application part cut along a first direction, the metal brushes formed on the first heat-generating applicator and the metal brushes formed on the second heat-generating applicator are located opposite to each other based on a first imaginary straight line B-B′. ### Claim 8 (depends on 6) The stick-type product having a heating function of claim 6, wherein based on a cross-section of the application part cut along a first direction, the first space in which the brush part is disposed is provided as a concave groove formed on the heat-generating applicator part. ### Claim 9 (depends on 6) The stick-type product having a heating function of claim 6, wherein based on a cross-section of the application part cut along a first direction, the metal brushes formed on the second heat-generating applicator are distributed to have a first angle based on a first imaginary straight line B-B′, the metal brushes disposed on one side and formed on the first heat-generating applicator are distributed to have a second angle based on the first imaginary straight line B-B′, and the metal brushes disposed on the other side and formed on the first heat-generating applicator are distributed to have a third angle based on the first imaginary straight line B-B′, and wherein the first angle is 180 degrees, and the second angle and the third angle are each between 1 degree and 60 degrees. ### Claim 10 (depends on 1) The stick-type product having a heating function of claim 1, wherein end portions of the metal brushes and at least portions of the non-metal brushes are in contact with each other. ### Claim 11 (depends on 1) The stick-type product having a heating function of claim 1, wherein the metal brushes are formed of a metal that is not deformed by an external force less than or equal to a certain magnitude applied by a user; and the non-metal brushes are formed of a material that is deformed by the external force. ### Claim 12 (depends on 1) The stick-type product having a heating function of claim 1, further comprising: a container configured to store the cosmetic article and accommodate the brush rod and the application part. ### Claim 13 (depends on 1) The stick-type product having a heating function of claim 1, wherein the metal brushes represent a temperature from 45° C. to 65° C. during operation of the stick-type product having a heating function. ### Claim 14 (depends on 1) The stick-type product having a heating function of claim 1, wherein based on a cross-section of the application part cut along a first direction, the metal brushes separated by a first distance from a center of the application part represent a specific temperature; and the non-metal brushes separated by the first distance from the center represent a temperature lower than the specific temperature. ### Claim 15 (depends on 1) The stick-type product having a heating function of claim 1, wherein the brush part includes: a first-connecting member coupled to the heat-generating applicator part; and a plurality of non-metal brushes coupled in a different direction relative to the direction in which the first connecting member extends, and wherein based on a cross-section of the application part cut along a first direction, the non-metal brushes are disposed only on one side relative to an imaginary straight line passing through the first connecting member.
