Provided are a vehicle body front portion structure and a method for manufacturing a vehicle body front portion, in which an instrument panel upper panel and a cowl side panel can be efficiently joined to an upper beam together without providing useless welding work holes. The lower edge portion of the cowl side panel (16) and the side wall of the upper split piece (20) are joined by a first joining portion (W1) to constitute an upper structure. The bent flange of the instrument panel upper plate (13) and the side wall of the upper beam base part (19) are jointed by a second joint part (W2) to form a base part structure body. With respect to the upper structure and the base structure, the lower edge portion of the cowl side panel and the edge portion of the cutout portion (18) of the base side wall (19s) are joined by a third joining portion (W3) to constitute a skeleton structure. With respect to the skeleton structure and the upper beam cover member (12), the upper and lower flange portions of the upper beam cover member (12) are joined to the upper wall of the upper split piece (20) and the lower wall of the upper beam base portion (19) by a fourth joining portion (W4) and a fifth joining portion (W5).

    提供一种车体前部结构及车体前部的制造方法,可不设置无用的焊接用的作业孔,而将仪表板上板与前围侧板一起高效率地接合于上梁。前围侧板(16)的下缘部与上部分割片(20)的侧壁由第一接合部(W1)接合而构成上部结构体。仪表板上板(13)的弯折凸缘与上梁基部(19)的侧壁由第二接合部(W2)接合而构成基部结构体。关于上部结构体与基部结构体,前围侧板的下缘部与基部侧壁(19s)的缺口部(18)的缘部由第三接合部(W3)接合而构成骨架结构体。关于骨架结构体与上梁盖构件(12),上梁盖构件(12)的上下的凸缘部由第四接合部(W4)及第五接合部(W5)接合于上部分割片(20)的上壁及上梁基部(19)的下壁。
