A start control device and a start control method of a vehicular power transmission system including a lock-up clutch and a start clutch are provided in which start-time lock-up slip control is performed, and neutral control is performed. When the start-time lock-up slip control is additionally executed during cancellation of the neutral control, the gradient of an output rotational speed of the hydraulic power transmission which is changed, through engagement of the start clutch, toward an input rotational speed of the automatic transmission at the time of completion of engagement of the start clutch is controlled, using at least one of a start clutch pressure that is increased so as to engage the start clutch, and a lock-up clutch pressure that is increased so as to bring the lock-up clutch into slip engagement.
