Abstract
An object is to provide a joining state detection film, a joining state detection device, and a joining state detection method, capable of detecting a joining state of a joining portion of two members from the outside. [Solution]A film containing a mechanoluminescent substance is formed on a surface, on a side opposite to a joining surface, of at least one member of two members that are joined at joining parts each having the joining surface, and physical stimulation is applied thereto.
Claims6
A joining state detection method for detecting a joining state of two members that are joined at joining parts each having a joining surface, the method comprising the steps of:
- forming the joining state detection film containing a mechanoluminescent substance on a first surface of a first of the two joining parts, the first surface being opposite to the joining surface of the first joining part;
- and
- physically stimulating the joining part such that light is emitted from a luminescent part of the joining state detection film and light is not emitted from a non-luminescent part of the joining state detection film and an area of the non-luminescent part indicates an area of the joining surface where the two members are not joined.
