Abstract: A condensation reaction-type die bonding agent has little liability of poor electrical connection at the electrodes. A condensation reaction-type die bonding agent for bonding an LED device provided on its surface with device electrodes having connection surfaces covered by gold, where the die bonding agent includes (A) a polysilsesquioxane solid in state at room temperature having trisiloxy units (TA) expressed by R1SiO3/2 where, R1 indicates one group selected from the group comprised of C1 to C15 alkyl groups, a phenyl group, and a benzyl group, and having hydroxyl groups, (B) a polysilsesquioxane liquid in state at room temperature having trisiloxy units (TB) expressed by R2SiO3/2 where, R2 indicates one group selected from the group comprised of C1 to C15 alkyl groups, a phenyl group, and a benzyl group, and having —OR2 where, R2 indicates one group selected from the group comprised of C1 to C15 alkyl groups, a phenyl group, and a benzyl group, and (C) a condensation reaction catalyst.

Abstract: A vehicle seat suitable as a straddle-type seat for a two or three-wheeled vehicle is provided, the straddle-type seat being configured to be shifted between a tip-up state and a seated state by a rotation mechanism, wherein there is no interference between the rotation mechanism and the seat. The vehicle seat of the present disclosure has a bottom plate, a seating portion, and a side portion. The seating portion and the side portion are covered by a surface material. In this vehicle seat configured to be shifted between the seated state and the tip-up state by the rotation mechanism, a recessed portion for the rotation mechanism is provided at the side portion facing the rotation mechanism.
