The cursor will bigger when user see closer object if I use default prefab , but I want to keep the cursor's size regardless of distance.

You can grab a reference to the cursor gameobject and set the transform.scale to alter it's size larger or smaller. To get the same relative perceived size, I think you would want to set the scale to some constant times the distance (x * distance), with distance being the length between the cursor and the camera.

You should definitely take a look at some basic Unity tutorials to get a better understanding of game objects and transforms. Unity Tutorials
You can grab a reference to your Cursor game object easily.public GameObject myCusror;then whenever you attach the script to something you just drag the Cursor game object onto the myCursor field in the Inspector Panel.To get the cursor's transform all you have to do is
myCursor.transform
A transform contains a lot of information but, the big three are position, rotation, and scale.As for distance, that is a method used to determine the distance between two Vectors.
float distance = Vector3.Distance(myCursor.transform.position, Camera.main.transform.position);AR Developer

Thank you so much for replying!
This might be basic question, but I don't know how to grab a reference to the cursor gameobject.
I installed "MixedRealityToolkit-Unity for Unity 2017.1.0f3" and am using its cursor object.
But I can't understand where the size of cursor or distances are written.
Could you tell me the name of script or some details?
