PROBLEM TO BE SOLVED: To provide an electric reel monitor case having higher waterproof properties and productivity than those of the prior art.SOLUTION: In a monitor case 31 of the invention, a case body 32 including a window part 39 is integrally molded in its entirety of a transparent mold so that the water immersion from the window part 39 is completely eliminated to enhance the waterproof property higher than that of the prior art and to make the deposition step of the prior art unnecessary to enhance the productivity. Moreover, the window part 39 protrudes from the outer face of the case body 32 and becomes thick so that the window part 39 can be strengthened without obstructing the visibility of the window part 39.
