A temperature sensor module comprising: a sensor unit having a sensing end for measurement of a temperature of a heat source; a heat conduction panel formed of a thermally conductive material and having a temperature measurement region connected to the sensing end and exposed to the heat source such that heat transferred from the heat source to the temperature measurement region is transferred to the sensing end along a surface of the temperature measurement region; and a heat insulation panel disposed opposite the heat source with respect to the heat conduction panel to prevent heat generated from the heat source or heat transferred to the heat conduction panel from being discharged to an outside of the heat insulation panel or to prevent external heat from being transferred to the heat conduction panel, wherein the heat conduction panel comprises a patterned portion forming at least a portion of the temperature measurement region, characterized in that the patterned portion comprises: a first patterned portion having a first inner region connected to the sensing end, a first outer region separated a first linear distance from the first inner region, and a first extension (2130, 2131, 2132) connecting the first inner region to the first outer region; and a second patterned portion having a second inner region connected to the sensing end, a second outer region separated from the second inner region by a second linear distance longer than the first linear distance, and a second extension (2230, 2231, 2232) connecting the second inner region to the second outer region. a sensor unit having a sensing end for measurement of a temperature of a heat source; a heat conduction panel formed of a thermally conductive material and having a temperature measurement region connected to the sensing end and exposed to the heat source such that heat transferred from the heat source to the temperature measurement region is transferred to the sensing end along a surface of the temperature measurement region; and a heat insulation panel disposed opposite the heat source with respect to the heat conduction panel to prevent heat generated from the heat source or heat transferred to the heat conduction panel from being discharged to an outside of the heat insulation panel or to prevent external heat from being transferred to the heat conduction panel, wherein the heat conduction panel comprises a patterned portion forming at least a portion of the temperature measurement region, characterized in that the patterned portion comprises: a first patterned portion having a first inner region connected to the sensing end, a first outer region separated a first linear distance from the first inner region, and a first extension (2130, 2131, 2132) connecting the first inner region to the first outer region; and a second patterned portion having a second inner region connected to the sensing end, a second outer region separated from the second inner region by a second linear distance longer than the first linear distance, and a second extension (2230, 2231, 2232) connecting the second inner region to the second outer region. a first patterned portion having a first inner region connected to the sensing end, a first outer region separated a first linear distance from the first inner region, and a first extension (2130, 2131, 2132) connecting the first inner region to the first outer region; and a second patterned portion having a second inner region connected to the sensing end, a second outer region separated from the second inner region by a second linear distance longer than the first linear distance, and a second extension (2230, 2231, 2232) connecting the second inner region to the second outer region.
