PROBLEM TO BE SOLVED: To provide a thruster for space capable of an intermittent operation using a solid propellant easy to handle in high density. SOLUTION: This solid propellant thruster for space includes solid propellant retaining means for retaining the solid propellant, a solid propellant deposit surface for depositing the solid propellant, solid propellant delivery means for delivering the solid propellant to a deposit position on the solid propellant deposit surface, deposit energy supply means for depositing the solid propellant of the deposit position on the solid propellant deposit surface with the solid propellant being heated to dissolution or sublimation, solid propellant transfer means for transferring the solid propellant to the release position for releasing it therefrom, and propelling energy supply means for accelerating the solid propellant in approximately the vertical direction from the solid propellant deposit surface of the release position and for releasing the solid propellant as a thruster jet by giving energy to the transferred solid propellant. Deposit portions of the solid propellant on the solid propellant deposit surface are recurrently restored near a part of the retained solid propellant by the solid propellant transfer means.
