A rubber member for laser bonding which comprises a rubber ingredient and silica, the silica having an average particle diameter of 50-120 nm, excluding 50 nm, and the amount of the silica being 10-50 parts by mass per 100 parts by mass of the rubber ingredient, and which has a laser light transmittance of 30% or higher. The laser light transmittance is a transmittance measured when the rubber member having a thickness of 2 mm is irradiated with laser light having a wavelength of 808 nm. Preferably, the silica comprises silica having an average particle diameter of 50-120 nm, excluding 50 nm, and silica having an average particle diameter of 5-50 nm, the amount of the silica with an average particle diameter of 50-120 nm, excluding 50 nm, being 10-50 parts by mass per 100 parts by mass of the rubber ingredient and the amount of the silica with an average particle diameter of 5-50 nm being 10-50 parts by mass per 100 parts by mass of the rubber ingredient. L'invention porte sur un élément en caoutchouc pour fixation au laser, lequel élément comprend un ingrédient de caoutchouc et de la silice, la silice ayant un diamètre de particules moyen de 50 à 120 nm, 50 nm exclus, et la quantité de la silice étant de 10 à 50 parties en masse pour 100 parties en masse de l'ingrédient de caoutchouc, et lequel a un facteur de transmission de la lumière de laser de 30 % ou plus. Le facteur de transmission de la lumière de laser est un facteur de transmission mesuré lorsque l'élément en caoutchouc, ayant une épaisseur de 2 mm, est irradié avec une lumière de laser ayant une longueur d'onde de 808 nm. De préférence, la silice comprend de la silice ayant un diamètre de particules moyen de 50 à 120 nm, 50 nm exclus, et de la silice ayant un diamètre de particules moyen de 5 à 50 nm, la quantité de la silice avec un diamètre de particules moyen de 50 à 120 nm, 50 nm exclus, étant de 10 à 50 parties en masse pour 100 parties en masse de l'ingrédient de caoutchouc, et la quantité de la silice avec un diamètre de particules moyen de 5 à 50 nm étant de 10 à 50 parties en masse pour 100 parties en masse de l'ingrédient de caoutchouc.
