PROBLEM TO BE SOLVED: To provide a toilet seat with bidet being attachable/detachable to/from a toilet stool and having a structure of detecting the presence of attachment/ detachment, achieving reliable attachment/detachment by preventing detecting malfunction. SOLUTION: The toilet seat 2 with bidet is detachably fixed to a base plate 3 fixed to the toilet bowl 1 with mounting bolts 34, and pawl portions 31, 32 provided on the insertion end face of the base plate is locked in engagement with hooks 41, 42 of an attaching/detaching operation lever 4 on the side of the toilet seat 2 with bidet. When a detected body 3a on the side of the base plate 3 and detecting means 2a on the side of the washing toilet seat with bidet are used for functioning the detection of the attachment/detachment, single- side lock and detecting malfunction are prevented by making the shapes of the hook 42 and the pawl portion 32 different from others. By the arrangement of a plurality of different-shape engagement portions, attachment/detachment detecting reliability is improved because of no detection as 'attachment' without locking all of them correspond to one another.
