Abstract: An electronic apparatus includes: a base; a functional element; and a first member and a second member which connect the base and the functional element to each other. The first member and the second member have different elastic moduli from each other. The elastic modulus of the first member is higher than the elastic modulus of the second member. At least a part of the first member is situated more closely to a center of the functional element than the second member, as viewed in a plan view taken from a direction in which the base and the functional element are arrayed.
