Inventive step is found.
The present invention and the cited invention have different problems to be solved.
There is no motivation to change the numerical value of the cited invention, and the ease of conceivability is denied.
In Japan, when the problems to be solved of the present invention and the cited invention are different from each other, easy conceivability tends be denied and inventive step tends to be found.
