PROBLEM TO BE SOLVED: To provide a tank of which a molding accuracy of a mouth is high and which can be manufactured with a good productivity while suppressing increase of a cost of manufacture, and a manufacturing method for the tank.SOLUTION: A tank made of a resin has a mouth. A tank body is formed by a blow molding, and an annular member, which is formed by, for example, injection molding, is bonded by deposition to a neck part of the tank body formed corresponding to the mouth. Further, a clearance is formed between the annular member and the tank body at an inner peripheral end part and an outer peripheral end part of the annular member. An interval of the clearance is 0.1 mm to 0.5 mm. In addition, a flange-like part is formed to the neck part of the tank body, and a corner part of the neck part of the tank body is brought into contact with an inclined plane of the annular member and deposited thereto. |
