As an intraoral sensor for X-ray photographing in an oral cavity, the present invention provides an intraoral sensor which is bent along a structure in the oral cavity in the X-ray photographing in the oral cavity, wherein the bending degree of a first region corresponding to a part toward a direction of a long axis is different from the bending degree of a second region which corresponds to the remaining region. Therefore, the present invention can reduce inconvenience of a patient by varying the bending degree of the intraoral sensor.본 발명은 구강 내 X선 촬영을 위한 인트라오럴 센서로서, 구강 내 X선 촬영 시 구강 내 구조물을 따라 휘어지고, 장축 방향을 향한 일부에 해당하는 제 1 영역과 나머지에 해당되는 제 2 영역의 휘어짐 정도가 다른 인트라오랄 센서를 제공한다.
