A speaker () includes a radiation surface (). The radiation surface () has a first region (), a second region (), and a third region () between the first region () and the second region (). When an axis passing through the third region () and extending away from the radiation surface () is defined as a reference axis (X), the speaker () forms a first wavefront () propagating from the first region so as to approach the reference axis (X) and a second wavefront () propagating from the second region () so as to approach the reference axis (X).

The present invention relates to a method for manufacturing a laminate, including: a laminating step of laminating a side of a thermal transfer layer of a thermal transfer sheet having a release sheet and the thermal transfer layer on at least a part of a surface of a resin member by heat bonding, in which the release sheet has no yield points, and has an elongation at break of 100% to 600% in a stress-strain curve measured by a tensile test at a molding temperature Tβ° C. in the laminating step.

A piezoelectric speaker () includes a piezoelectric film (), a first joining layer (), and an interposed layer (). The piezoelectric film () includes a first electrode (), a second electrode (), and a piezoelectric body () sandwiched by the first electrode () and the second electrode (). The first joining layer () is a layer having pressure-sensitive adhesiveness or adhesiveness. The interposed layer () is disposed between the piezoelectric film () and the first joining layer (). Both principal surfaces of the piezoelectric film () vibrate up and down as a whole.
