A plate-like-object manufacturing method, plate-like objects, a gas-turbine combustor, and a gas turbine, in which degradation in the cooling performance can be suppressed, the time required for manufacturing a gas-turbine combustor can be shortened, and deterioration of the working environment can be prevented are provided. A plate-like-object manufacturing method includes a step of forming a plate-like object by stacking a plurality of plates and arranging a plurality of channels, through which a cooling medium flows, side-by-side between the plurality of plates; and a step of arranging a plurality of the plate-like objects side-by-side in a direction in which the channels are arranged, butting the plurality of plate-like objects against each other, and performing welding at an abutment section. The channels adjacent to the abutment section extend along the abutment section and have a greater dimension in the direction in which the channels are arranged, as compared with that of other channels.

1. A plate-like-object manufacturing method comprising: a step of forming a plate-like object by stacking a plurality of plates and arranging a plurality of channels, through which a cooling medium flows, side-by-side between the plurality of plates; anda step of arranging a plurality of the plate-like objects side-by-side in a direction in which the channels are arranged, butting the plurality of plate-like objects against each other, and performing welding at an abutment section, the plurality of the plate-like objects forming a portion of a combustor,wherein the channels adjacent to the abutment section, which are arranged with a predetermined interval from the welding in the direction in which the channels are arranged, extend along the abutment section and have a greater dimension in the direction in which the channels are arranged, as compared with that of other channels. 2. The plate-like-object manufacturing method according to claim 1, wherein the step of forming the plate-like object comprises: a step of forming a plurality of grooves side-by-side in one surface of one plate; anda step of forming the plate-like object and the plurality of channels by joining another plate to the one surface of the one plate. 3. The plate-like-object manufacturing method according to claim 1, wherein the step of forming the plate-like object comprises: a step of forming a plurality of slits side-by-side in a first plate; anda step of forming the plate-like object and the plurality of channels by joining second plates to one surface and another surface of the first plate. 4. A gas-turbine combustor comprising: a nozzle unit that emits fuel; anda cylindrical object that mixes and combusts air and the emitted fuel therein,wherein the cylindrical object comprises the plate-like objects manufactured by the plate-like-object manufacturing method according to claim 1. 5. A gas turbine comprising: a compressor that compresses air;the gas-turbine combustor according to claim 4 that produces combustion gas by mixing and combusting compressed air supplied from the compressor and fuel supplied from the outside;a turbine unit that converts a portion of energy included in the combustion gas into a rotational driving force; anda rotating shaft that transmits the rotational driving force from the turbine unit to the compressor. 6. Plate-like objects comprising: one plate-like object having a plurality of channels arranged side-by-side therein;another plate-like object having a plurality of channels arranged side-by-side therein, the plurality of channels being arranged side-by-side in one direction relative to the one plate-like object; anda welded section at which the one plate-like object and the other plate-like object are joined together,wherein the channels adjacent to the welded section for the one plate-like object and the other plate-like object, which are arranged with a predetermined interval from the welded section in the direction in which the channels are arranged, and extending along the welded section have a greater dimension in the direction in which the channels are arranged, as compared with that of other channels, andwherein the one plate-like object and the another plate like object form a portion of a combustor. 7. A gas-turbine combustor comprising: a nozzle unit that emits fuel; anda cylindrical object that mixes and combusts air and the emitted fuel therein, wherein the cylindrical object comprises the plate-like objects according to claim 4. 8. A gas turbine comprising: a compressor that compresses air;the gas-turbine combustor according to claim 7 that produces combustion gas by mixing and combusting compressed air supplied from the compressor and fuel supplied from the outside;a turbine unit that converts a portion of energy included in the combustion gas into a rotational driving force; anda rotating shaft that transmits the rotational driving force from the turbine unit to the compressor.
