Collimator module manufacturing method, collimator module, radiation detection device, and radiation imaging device

The invention relates to a collimator module, a manufacturing method thereof, a radiation detection device and a radiation imaging device are provided. The method includes aligning a plurality of collimator plates (3) arranged a predetermined distance apart in one direction, each of the collimator plates being substantially a rectangular solid, bonding a first bar-like member (4) to upper edges (3b) of the collimator plates (3), the first bar-like member (4) being radiolucent and extending from a first collimator plate at a first end to a second collimator plate at a second end in the direction of the collimator plate arrangement, and bonding a second bar-like member (5) to the lower edges (3c) of the collimator plates (3), the second bar-like member (5) being radiolucent and extending from the first collimator plate to the second collimator plate.
