PROBLEM TO BE SOLVED: To provide a moving object measuring apparatus which can precisely acquire the moving information on a moving object such as a golf club head or a golf ball moving with the degree of spinning. SOLUTION: As an example of the moving object measuring apparatus, a head measuring apparatus 10 has a half mirror 34, an irradiation light source 32 which irradiates the golf club head with the light sent from the half mirror 34 after emission to the half mirror 34, a camera 32 which captures the image by the reflected light of a reflection marker provided on the golf club head through the half mirror 34 and a moving information calculation part 14 which calculates the moving information on the golf club head from the image of the reflection marker captured by the camera 32. The arrangement of the irradiation light source 32, the camera 36 and the half mirror 34 is adjusted to make the angle of emission of the irradiation light emitted from the interface of the half mirror 34 almost match the angle of incidence of the reflected light from the reflection marker into the interface of the half mirror 34.
