The bowl 11 of the filter housing 10 is configured to include: a cylindrical side part 11a; an opening part 11b which is located on one end side of the side part 11a and to which the head 13 is attached; and a bottom part 11c that seals the other end side of the side part 11a. The side part 11a has a taper-shaped section 16 that is tapered from the opening part 11b side toward the bottom part 11c side. A joint surface 18 for increasing a cross-sectional area by extending, over the entire circumference, to the outer circumferential side with respect to the outer surface of the taper-shaped section 16 and/or to the inner circumferential side with respect to the inner surface of the taper-shaped section 16, is formed midway in the axial direction of the taper-shaped section 16 so as to be oriented toward the opening part 11b side.
