PROBLEM TO BE SOLVED: To provide a screen speaker in which screen speaker deformation is suppressed by reducing a difference in a deformation amount, caused by a temperature change, between a screen and a support. SOLUTION: A screen (S) of a screen speaker (10) and a support (20) supporting said screen (S) are constructed from the same metal material such as aluminum, together and are configured so that their thermal expansion coefficients are identical or approximately equal to each other.
