Encapsulating film, encapsulating film-coated electronic component mounting board and electronic equipment

摘要

PROBLEM TO BE SOLVED: To provide a sealing film capable of maintaining light transmission for a long period of time even when the sealing film is exposed to ultraviolet rays, and for sealing including such a sealing film. To provide a film-coated electronic component mounting substrate and a highly reliable electronic device including such a film-coated electronic component mounting substrate for sealing. SOLUTION: The sealing film 100 of the present invention has a light transmittance used for coating an electronic component mounting substrate 45, is composed of a resin material as a main material, and uses an eye super UV tester. It is satisfied that the haze value measured according to JIS K 7105 after irradiation with ultraviolet rays for 100 hours is 5% or more and 10% or less. [Selection diagram] Fig. 2
