PROBLEM TO BE SOLVED: To provide a header device of a heat transfer tube and a boiler capable of reducing temperature distribution in the width direction of the heat transfer tube and preventing the heat transfer tube from having a problem due to heat stress. SOLUTION: This header device of the heat transfer tube for mixing fluids flowing therein from a plurality of first heat transfer tubes and distributing the mixed fluid to a plurality of second heat transfer tubes, includes a gas-liquid separator connected with the plurality of first heat transfer tubes for separating the gas-liquid two phase fluid flowing therein from the plurality of first heat transfer tubes into a gas and a liquid, a plurality of distribution tubes connected with the gas-liquid separator, mixing the gas and the liquid separated by the gas-liquid separator, and distributing the mixed fluid to deliver the same to the second heat transfer tubes, and a gas-liquid ratio adjustment means for adjusting a gas-liquid ratio of the gas and the liquid.
