Abstract: A metal substrate supported by a wiring substrate includes a first extending portion and a first connection portion connected to the first extending portion. The first connection portion includes a first region facing a portion of a wiring substrate in a Z-axis direction, a second region being continuous from the first region, and a third region being continuous from the second region. When viewed in the Z-axis direction, in a direction perpendicular to a connection direction in which the third region is connected to the second region, a width of the second region is larger than a width of the third region. A first bonding member bonding the wiring substrate and the metal substrate includes a first portion disposed between the portion and the first region, and a second portion being continuous from the first portion. The second portion reaches the second region but does not reach the third region.

Abstract: A mirror device includes a support portion, a movable portion, and a pair of torsion bars disposed on both sides of the movable portion on a first axis. The movable portion includes a frame-shaped frame connected to the pair of torsion bars and a mirror unit disposed inside the frame. The mirror unit is connected to the frame in each of a pair of connection regions located on both sides of the mirror unit in a direction parallel to a second axis. A region other than the pair of connection regions in a region between the mirror unit and the frame is a space. An outer edge of the mirror unit and an inner edge of the frame are connected to each other so that a curvature in each of the pair of connection regions is continuous when viewed from a direction perpendicular to the first and the second axes.

Abstract: A piezoelectric drive element disposed on a placement surface of a metal substrate includes a piezoelectric drive body having a first main surface opposite the placement surface, a second main surface on a placement surface side, and a side surface, and a first electrode disposed on the first main surface. The piezoelectric drive element is disposed on the placement surface such that a part of the placement surface is located outside the side surface. A second bonding member having conductivity includes a first portion disposed between the placement surface and the piezoelectric drive element, and a second portion being continuous from the first portion and disposed in a corner formed by the part of the placement surface and the side surface. The second portion does not reach the first electrode.
