PROBLEM TO BE SOLVED: To improve peel resistance of a marker for a mobile object with a marker fixed thereto for reflecting light.SOLUTION: A mobile object 2 is used in a detection method of a mobile object including the steps of: imaging by a camera a mobile object 2 with a marker 30 fixed thereto having a reflection surface 32 for reflecting light; and detecting a posture of the mobile object 2 on the basis of the imaged marker 30. The marker 30 includes: the reflection surface 32; a fixed surface 34 that is positioned on the opposite side to the reflection surface 32 and is fixed to the mobile object 2; and a side surface 36 that joins the reflection surface 32 and the fixed surface 34. The side surface 36 of the marker 30 is inclined to a direction to be a tapered shape from the fixed surface 34 toward the reflection surface 32 in a transverse plane perpendicular to the reflection surface 32. |
