Magnetosonic shock wave propagating obliquely to a magnetic field is studied by theory and simulation, with particular attention to the resonant ion acceleration (the ν_p×B acceleration) by the shock. Theoretical analysis based on a two fluid model shows that, in the laminar shock, the electric field strength in the direction of the wave normal is about (m_i/m_e)^<1/2> times larger for the quasi-perpendicular shock than that for the quasi-parallel shock, which is a reflection of the fact that the width of the quasi-perpendicular shock is much smaller than that of the quasi-parallel shock. Time evolution of a totally self-consistent magnetosonic shock wave is studied by using a 2-1/2 dimensional fully relativistic, fully electromagnetic particle simulation with full ion and electron dynamics. Even the low Mach number shock wave can significantly accelerate some ions by the ν_p×B acceleration. The resonant ion acceleration occurs more strongly in the quasi-perpendicular shock, because the magnitude of this acceleration is proportional to the electric field strength.
