Abstract: A sealing acrylic resin composition contains a thermosetting acrylic resin in liquid phase, an organic peroxide, and an inorganic filler in a content proportion ranging from 50% by mass to 95% by mass, inclusive. A silane coupling agent is bonded to the inorganic filler, a total organic carbon content of the inorganic filler in proportion being ranging from 0.1% by mass to 1.0% by mass, inclusive, in a state before the inorganic filler is mixed with at least one of the thermosetting acrylic resin and the organic peroxide. The silane coupling agent has an acrylic group.
