ILC will be a unique facility when once it has come. While the main purpose of ILC is concentrated on the high-energy physics for the time being, it should be very useful to consider diversified usages of the facility among the wide science fields. In order to reveal variety of ideas towards the diversified applications, a workshop “ILC diversified application” was held on 29-30th, November 2017 at 2 go-kan, KEK.
