1. An optical member driving mechanism for connecting an optical member, comprising:
a fixed portion, comprising:
a first member; and
a second member, fixedly connected to the first member;
a first adhesive member, wherein the first member is fixedly connected to the second member via the first adhesive member;
a movable portion, configured to connect the optical member;
a driving assembly, configured to drive the movable portion to move relative to the fixed portion;
a second adhesive member, wherein the first member is fixedly connected to the second member via the second adhesive member;
a first gap, formed between the first member and the second member and configured to receive the first adhesive member; and
a second gap, configured to receive the second adhesive member;
wherein:
as seen from an exterior of the optical member driving mechanism, at least a portion of the second gap is exposed, and at least a portion of the second adhesive member is exposed;
a shortest distance between the first member and the second member in the first gap is different from a shortest distance between the first member and the second member in the second gap;
the first gap is communicated with the second gap;
a receiving space is formed between the first member and the second member, and the receiving space is configured to receive the movable portion;
a shortest distance between the first gap and the receiving space is different from a shortest distance between the second gap and the receiving space;
a viscosity of the uncured first adhesive member is different from a viscosity of the uncured second adhesive member.
