A transformer (1) comprises: a core (10) to at least a part of which a gap (11) is provided and which forms a magnetic circuit; a bobbin (20) that is mounted to the core (10); a first winding wire (31) that is wound by being divided into two or more layers including a layer (31a) wound on a side closest to the gap (11) of the bobbin (20) and a layer (31b) wound on a side farther from the gap (11);and a second winding wire (32) that is insulated from the first winding wire (31) and that includes a layer (32a) on the second winding wire (32) side wound between the layer (31a) and the layer (31b) on the first winding wire (31) side, wherein the layer (31a) and the layer (31b) of the first winding wire (31) are connected in series. 变压器(1)具备：铁芯(10)，其形成磁路，并且至少一部分设置有间隙(11)；绕线架(20)，其被安装于该铁芯(10)；第一绕组(31)，其被成两层以上进行卷绕，所述两层以上包括被卷绕在该绕线架(20)的离间隙(11)最近的一侧的层(31a)和被卷绕在比该层(31a)离间隙(11)远的一侧的层(31b)；和第二绕组(32)，其包括被卷绕在第一绕组(31)侧的层(31a)与层(31b)之间的第二绕组(32)侧的层(32a)，与第一绕组(31)绝缘，所述第一绕组(31)的层(31a)与层(31b)被串联连接。
