To secure good sealing performance by press-fitting of a sealing plug in consideration of the influence of swelling due to fuel without using an elastic member.SOLUTION: A fuel passage sealing structure for a fuel supply device is composed of a fuel passage 28 for the fuel supply device, which is formed inside a resin fuel passage forming portion (fuel passage constituting member) 30, an opening 40 in which one end of the fuel passage 28 is formed as an opening shape to the outside, and a sealing plug 36 that is fitted into the opening 40 to seal the fuel passage 28. The sealing plug 36 is made of the same resin as the fuel passage forming portion 30, and is attached to the opening 40 of the fuel passage 28 by press-fitting, and in a range L in which the sealing plug 36 and the opening 40 are press-fitted to each other, formed thicknesses V1, V2 of them are the same.SELECTED DRAWING: Figure 5
