A bodily information measurement apparatus includes: a belt for wrapping around a measurement site； a main body arranged at a base end portion in a lengthwise direction of the belt and on which an element that measures bodily information is mounted； and a buckle for joining the base end portion and a leading end portion of the belt such that the belt forms a loop shape. The buckle includes first and second plate frame members, which include, respectively, first and second opening portions that penetrate through the respective members with respect to a plate surface. In a state in which the inner surface of the main body and the first and second plate frame members of the buckle are folded in so as to overlap, the first and second opening portions of the first and second plate frame members, respectively, are continuous in a thickness direction of the main body.
