The objective of the present invention is to enable an improvement in the bonding strength of a first molded member and a second molded member in an injection molded body. A lamp 1 includes: a housing 2 provided with an accommodating portion 2a for accommodating a sealed member; a lens 3 which covers the accommodating portion 2a, and which is bonded to the housing 2; and a resin bonding material 9 which is in contact with the housing 2 and the lens 3, and which bonds the housing 2 to the lens 3. Furthermore, the housing 2 is provided, as the accommodating portion 2a, with a first accommodating portion 2b having an elongate shape, and a second accommodating portion 2c having an accommodating part that is wider than the first accommodating portion 2b, wherein a first abutting surface of the housing 2 in the second accommodating portion 2c, and a second abutting surface of the lens 3 are formed such that the respective surfaces thereof have an undulating shape. The resin bonding material 9 is in contact with a protruding surface of the housing 2, and a wall portion 3b of the lens 3.
本发明能够提高射出成形体中的第一成形构件与第二成形构件的接合强度。灯1具有:壳体2,设有收容封入构件的收容部2a;透镜3,覆盖收容部2a且与壳体2接合;以及树脂接合材9,接触至壳体2与透镜3而接合壳体2与透镜3。并且,壳体2包括细长形状的第一收容部2b与收容部分的宽度比第一收容部2b宽的第二收容部2c来作为收容部2a,第二收容部2c中的壳体2的第一抵接面以及透镜3的第二抵接面彼此的面形成为凹凸状。树脂接合材9接触至壳体2的突出面与透镜3的壁部3b。
