Claim 3:
4. An illumination device comprising:
a light guide including a first plane, a first tilted plane tilted to the first plane connected to the first plane and, a second plane opposed to the first plane and substantially parallel to the first plane, a second tilted plane opposed to the first plane, connected to the second plane and tilted to the second plane, and a side plane, an angle formed between the first plane and the first tilted plane and an angle formed between the second plane and the second tilted plane being obtuse angles;, smaller than 180 degrees;
a first reflective layer disposed on the first tilted plane;
a second reflective layer disposed on the second tilted plane;
a first semiconductor laser element including a first base and a first light emitting part; and
a second semiconductor laser element including a second base and a second light emitting part,
wherein
the light guide is located between the first light emitting part and the second light emitting part,
the first light emitting part is opposed to the first tilted plane,
the second light emitting part is opposed to the second tilted plane, and
a thickness of the light guide in an area where the first plane and the second tilted plane are opposed to each other, is decreased toward the side plane.
