PROBLEM TO BE SOLVED: To heighten the degree of design freedom as well as completion in a rim shot type flush toilet bowl constituted to jet wash water horizontally along the inner side ground of a rim part from a wash water jet port provided near a joint part between the rim part and a bowl part. SOLUTION: A side face hollow part surrounded by an upper face wall 21a, a side face wall 21b and an inner surface wall 21k is formed inside the side face of a rim part 21, along the nearly whole periphery of the side face wall 21b on the front side of a storage part 12. In a rim part base 10a before baking, an angleθ1 defined by the upper face wall 21a and the inner surface wall 21k can thereby be formed as a different angle from an angleθ2 defined by the upper face wall 21a and the side face wall 21b.
