PURPOSE:To obtain a scintillation camera whose positional resolution is improved sharply in comparison with conventional ones and which enables prevention of formation of a shadow of an inner piece of a collimator. CONSTITUTION:A collimator element 1, a fiber-containing collimator element 2 into which a plastic scintillator 7 is inserted, position-sensitive PMT 3 and a moving mechanism 11 are provided. The collimator element 1 and the fiber- containing collimator element 2 are moved minutely to the right and the left repeatedly in relation to the PMT 3 by the moving mechanism 11.
