Abstract: A flush toilet includes a toilet main body made of ceramics, a control unit, a supply source that enables water supply or power supply to the control unit, and a flexible elongated member connecting the supply source and the control unit. The toilet main body includes a rear storage configured to store at least a part of the control unit. The rear storage includes an upper storage region, a lower region, and a lower communication region. The flexible elongated member extends from an upper connecting end portion toward a lower connecting end portion, to be inserted from the upper storage region into the lower communication region, and then extends from inside of the lower communication region to outside of the toilet main body, without extending through the lower region.

Abstract: A flush toilet which is capable of suppressing reduction in the force of water and disturbance in the flow curved by a pressure loss caused by a flow curved separating from a surface on an inner side portion side of an intermediate part. A rim water passage of the flush toilet includes a curved portion that is curved inward from a downstream end of an outer side portion. The curved portion includes a top portion that is at a position farthest from the intermediate part in the top view, in a direction extending the intermediate part. The top portion is formed in more the outer side portion side than a virtual center line that extends along a center of the intermediate part.

Abstract: A flush toilet includes a toilet main body made of ceramics and a control unit. The toilet main body includes a skirt, and a rear storage that can store at least a part of the control unit, the rear storage includes a supporting wall that divides a storage region into upper and lower regions and that supports the control unit, the skirt forms a double wall including an outer wall and an inner wall, the double wall has at least a part that forms an internal space between the outer wall and the inner wall, and the skirt includes a single wall in which the internal space of the double wall is removed in an upper end above a joining portion between the double wall and the supporting wall.
