Adhesive sheet for provisional fixation of electronic component

Abstract

Provided is a pressure-sensitive adhesive sheet for temporarily fixing an electronic part that shows peelability by irradiation with light, the pressure-sensitive adhesive sheet for temporarily fixing an electronic part having a wide range of selection of the light to be applied. The pressure-sensitive adhesive sheet for temporarily fixing an electronic part of the present invention includes: a laminated structure A including a first photothermal conversion layer and a second photothermal conversion layer arranged on at least one side of the first photothermal conversion layer; and a pressure-sensitive adhesive layer arranged on at least one side of the laminated structure A. The pressure-sensitive adhesive sheet has a transmittance for light having a wavelength of 1,032 nm of 75% or less, and has a transmittance for light having a wavelength of 355 nm of 50% or less.
