Toilet bowl

Provided is a toilet bowl capable of improving dirt discharge performance. The water storage surface (31) of the recessed portion (17) is viewed from above in a plan view. A line passing through the center of the water storage surface in the left-right direction is used as an imaginary vertical line (L1), a line passing through the center of the water storage surface in the front-back direction is used as an imaginary transverse line (L2), and a point where the imaginary vertical line and the imaginary transverse line intersect is used as a center point (D). Two lines passing through the center point at an angle of 45 degrees with respect to the imaginary vertical line and the imaginary transverse line are used as imaginary oblique lines (L3), when the water storage surface is divided into four pieces by the imaginary oblique lines, a front region (40) is used as a front region, a rear region (41) is used as a rear region, a region located on the first side among the left and right regions is used as a first
