An example input apparatus includes an elastic member, a base portion and a strain gauge. The elastic member includes a first end portion and a second end portion, and at least a part of the elastic member is elastically deformable. The base portion holds the opposite end portions of the elastic member so that a ring is formed by the base portion and the elastic member. The strain gauge is provided on the base portion and detects a strain generated on the base portion due to deformation of the elastic member in response to an input from the user. Note that instead of the configuration where a ring is formed by the base portion and the elastic member, the input apparatus may be configured so that two elastic members are held by the base portion.
