Abstract: A metal-resin composite body (100) of the present invention is obtained by bonding a resin member (101) and a metal member (102) together. The resin member (101) is obtained by curing a thermosetting resin composition (P) containing a thermosetting resin (A) and a filler (B). The metal member (102) has a roughened layer (104) including fine irregularities on at least a bonding surface (103) bonded to the resin member (101). A portion of the filler (B) is present in depression portions constituting the irregularities of the roughened layer (104).

Abstract: A thermosetting resin composition (P) of the present invention is used for forming a resin member (101) in a metal-resin composite body (100) including the resin member (101) and an aluminum-based metal member (102) bonded to the resin member (101) and contains a thermosetting resin (A) and a filler (B), in which a rate of change of warpage is equal to or greater than ?35% and equal to or less than 35%.

Abstract: In a metal resin composite body (100) of the present invention, a resin member (101) and a metal member (102) are joined, and the metal resin composite body (100) is obtained by joining the resin member (101) and the metal member (102). The resin member (101) is formed of a thermosetting resin composition (P) including a thermosetting resin (A) as a resin component. In the metal member (102), a ratio of a real surface area by using a nitrogen adsorption BET method to an apparent surface area of a joining surface (103) joining to at least the resin member (101) is greater than or equal to 100 and less than or equal to 400.

Abstract: In a metal resin composite body (100) of the present invention, a resin member (101) and a metal member (102) are joined, and the metal resin composite body (100) is obtained by joining the resin member (101) and the metal member (102). The resin member (101) is formed of a thermosetting resin composition (P) including a thermosetting resin (A) as a resin component. In the metal member (102), glossiness of a joining surface (103) joining to at least the resin member (101) is greater than or equal to 0.1 and less than or equal to 30. Here, the glossiness indicates a value of a measurement angle of 60° which is measured on the basis of ASTM-D523.

Abstract: There is provided a wavelength-converting composition and a photovoltaic device in which a wavelength-converting substance can be uniformly dispersed without causing an increase in manufacturing costs. The wavelength-converting composition contains a curing resin and a wavelength-converting substance for converting the wavelength of absorbed light.
