The invention relates to a lanthanum bromide crystal detector for detecting outer space gamma rays. The lanthanum bromide crystal detector is provided with a scintillating crystal and signal readout equipment thereof, wherein a packaging shell is arranged outside the scintillating crystal; glass is arranged on the light emergent surface of the packaging shell; the lanthanum bromide crystal detector is characterized in that the scintillating crystal is in a form of a lanthanum bromide crystal; a filling material is filled between the lanthanum bromide crystal and the packaging shell thereof; the filling material is composed of an elastic silicon optical coupling agent, magnesium oxide and titanium oxide according to the weight ratio of (4-6):(4-6):1; and the thickness of the filling material is 3-4 mm. According to the lanthanum bromide crystal detector disclosed by the invention, the disadvantage that the lanthanum bromide crystal detector in the prior art only can be used in a ground observation instrument c
