PROBLEM TO BE SOLVED: To provide a panoramic image block having a structure capable of easily supporting and fixing angles of view, etc., without narrowing the angles of views, etc. SOLUTION: This panoramic image block is a rotary body consisting of a light transparent blank including a front light shielding surface 1 at the center of a front surface, a front translucent surface 3 at the peripheral edge of the front surface, a rear light shielding surface 2 at the peripheral edge of a rear surface and a rear translucent surface 4 at the central part of the rear surface. The rear light shielding surface 2 is formed as a reflecting mirror capable of collecting the incident light from the front translucent surface 3 through the rotary body to the front light shielding surface 1; the front light shielding surface 1 is formed as a reflecting mirror capable of collecting the reflected light from the rear light shielding surface 2 through the inside of the rotary body to the rear translucent surface 4 and the outer edge of the front translucent surface 3 includes a supporting section 5 protruding form the outer edge of the rear light shielding surface 2.
