PROBLEM TO BE SOLVED: To provide a fruit tree protective device which contributes effectively to resource saving by reducing the total cost such as equipment cost and work cost associated with installation, and reducing waste of equipment materials. SOLUTION: For equipment materials selected to have a predetermined mesh size and formed in a predetermined outer shape F, a branch Tb of a fruit tree T or a branch Tb and / or a fruit tree T. Prepare one or more fruit tree protective devices 1 provided with a plurality of hook members, which are attached and detached by a hooking method and attached at predetermined intervals along the outer peripheral edge of the net member 2, and the hook members are attached to the fruit tree. By hooking on the branch Tb and / or the equipment material of T, the net member 2 covers at least the opening space S in the fruit tree T where birds and beasts can invade the inside of the fruit tree T.
